CLNDR is a jQuery calendar plugin. It was created- you've heard this before- out of frustration with the lack of truly dynamic front-end calendar plugins out there.
See a demo: kylestetz.github.io/CLNDR/
If you are using clndr.js and have any feedback or ideas about a new version, please take a moment to contribute to #151. If you are interested in helping to develop the new version, give a shout in #136. Thanks!

jQuery and Moment.js are depended upon. By default CLNDR tries to use Underscore.js's _.template() function, however if you specify a custom rendering function (see documentation below) underscore will not be used at all.
Because their APIs are the same, Lo-Dash's _.template() function will work as well! Just include Lo-Dash instead of underscore.
You can install CLNDR via Bower:
bower install clndrUnderscore is not installed by default. This allows you to use whichever templating engine you want to. If you want to use the default template option with Underscore, just install it as a dependency of your project: bower install underscore.
If you want to integrate clndr into an angular.js site, get started with this directive: angular-clndr.
If you're building a rails application you may be interested in this gem by @sedx: clndr-rails.
There are wonderful and feature-rich calendar modules out there and they all suffer the same problem: they give you markup (and often a good heap of JS) that you have to work with and style. This leads to a lot of hacking, pushing, pulling, and annoying why-can't-it-do-what-I-want scenarios.
CLNDR doesn't generate markup (well, it has some reasonable defaults, but that's an aside). Instead, CLNDR asks you to create a template and in return it supplies your template with a great set of objects that will get you up and running in a few lines.
Here's a typical CLNDR template. It's got a controller section and a grid section.
<div class="clndr-controls">
<div class="clndr-previous-button">‹</div>
<div class="month"><%= month %></div>
<div class="clndr-next-button">›</div>
</div>
<div class="clndr-grid">
<div class="days-of-the-week">
<% _.each(daysOfTheWeek, function(day) { %>
<div class="header-day"><%= day %></div>
<% }); %>
<div class="days">
<% _.each(days, function(day) { %>
<div class="<%= day.classes %>"><%= day.day %></div>
<% }); %>
</div>
</div>
</div>The days array contains most of the stuff we need to make a calendar. Its structure looks like this:
{
day: 5,
classes: "day",
events: [],
date: moment("2013-05-29")
}This makes quick work of generating a grid. days.classes contains extra classes depending on the circumstance: if a given day is today, 'today' will show up, as well as an 'event' class when an event lands on that day.
CLNDR accepts events as an array of objects:
events = [
{ date: "YYYY-MM-DD or some other ISO Date format", and: "anything else" }
]CLNDR looks through the objects in your events array for a date field unless you specify otherwise using the dateParameter option. In your template the days array will auto-magically contain these event objects in their entirety. See the examples for a demonstration of how events populate the days array.
CLNDR leans on the awesome work done in underscore.js and moment.js- these are requirements (unless you are using a different rendering engine, in which case underscore is not a requirement). Do be sure to include them in your <head> before clndr.js. It is a jQuery plugin, so naturally you'll need that as well.
The bare minimum (CLNDR includes a default template):
$('.parent-element').clndr();With all of the available options:
$('.parent-element').clndr({
// the template: this could be stored in markup as a
// <script type="text/template"></script>
// or pulled in as a string

// determines which month to start with using either a date string or a
// moment object.
startWithMonth: "YYYY-MM-DD" or moment(),
// start the week off on Sunday (0), Monday (1), etc. Sunday is the default.

// don't want this! See the "Internationalization" section below for more.

});All of the things you have access to in your template:

daysOfTheWeek: ['S', 'M', 'T', etc...]
// the number of 7-block calendar rows,
// in the event that you want to do some looping with it

// month.substring(0, 1) and month.toLowerCase() in your template
previousMonth: "April"

year: "2013"
// all of the events happening this month

eventsLastMonth: [ ],
// all of the events happening next month
eventsNextMonth: [ ],
// anything you passed into the 'extras' property when creating the clndr
extras: { }Clndr accepts events lasting more than one day. You just need to tell it how to access the start and end dates of your events:
var lotsOfEvents = [
{ start: '2013-11-04', end: '2013-11-08', title: 'Monday to Friday Event' },
{ start: '2013-11-15', end: '2013-11-20', title: 'Another Long Event' }
];
$('#calendar').clndr({
events: lotsOfEvents,
multiDayEvents: {
startDate: 'start',
endDate: 'end'
}
});When looping through days in my template, 'Monday to Friday Event' will be passed to every single day between the start and end date. See index.html in the example folder for a demo of this feature.
If you also have single-day events mixed in with different date fields, as of clndr v1.2.7 you can specify a third property of multiDayEvents called singleDay that refers to the date field for a single-day event.
var lotsOfMixedEvents = [
{ start: '2015-11-04', end: '2015-11-08', title: 'Monday to Friday Event' },
{ start: '2015-11-15', end: '2015-11-20', title: 'Another Long Event' },
{ date: '2015-07-16', title: 'Birthday' }
];
$('#calendar').clndr({
events: lotsOfEvents,
multiDayEvents: {
startDate: 'start',
endDate: 'end',
singleDay: 'date'
}
});
The classes that get added to a day object automatically can be customized to avoid styling conflicts. The classes option accepts today, event, past, lastMonth, nextMonth, adjacentMonth, and inactive. Pass in only the classnames you wish to override and the rest will be set to their defaults.
In this example we create a my- namespace for all of the classes:
clndr.customClasses = $('#custom-classes').clndr({
classes: {
today: "my-today",
event: "my-event",
past: "my-past",
lastMonth: "my-last-month",
nextMonth: "my-next-month",
adjacentMonth: "my-adjacent-month",
inactive: "my-inactive"
}
});To configure the day, empty, and next/previous/today/etc. button classes, use the targets option documented in the usage section.
If you are making a datepicker or you'd just like to prevent users from nexting all the way to 2034 in your calendar, you can pass a constraints option with startDate, endDate, or both specified:
$('#calendar').clndr({
constraints: {
startDate: '2015-05-06',
endDate: '2015-07-16'
}
})Now your calendar's next and previous buttons will only work within this date range. When they become disabled they will have the class 'inactive', which you can use to gray them out or add gif flames or whatever.
The days in your grid that are outside of the range will also have the inactive class. This means that you will want to add a click callback and check for whether or not a day has the class inactive. It will look like this:
$('#calendar').clndr({
constraints: {
startDate: '2015-05-06',
endDate: '2015-07-16'
},
clickEvents: {
click: function(target) {
if( !$(target.element).hasClass('inactive') ) {
console.log('You picked a valid date!');
} else {
console.log('That date is outside of the range.');
}
}
}
})The constraints can be updated at any time via clndr.options.constraints. If you make a change, call render() afterwards so that clndr can update your interface with the appropriate classes.
myCalendar.options.constraints.startDate = '1999-12-31';
myCalendar.render();Make sure the startDate comes before the endDate!
It's possible to save the clndr object in order to call it from JS later. There are functions to increment or set the month or year. You can also provide a new events array.
// Create a Clndr and save the instance as myCalendar
var myCalendar = $('#myCalendar').clndr();
// Go to the next month
myCalendar.forward();
// Go to the previous month
myCalendar.back();
// Set the month using a number from 0-11 or a month name
myCalendar.setMonth(0);
myCalendar.setMonth('February');
// Go to the next year
myCalendar.nextYear();
// Go to the previous year
myCalendar.previousYear();
// Set the year
myCalendar.setYear(1997);
// Change the events. Note that this triggers a re-render of the calendar.
myCalendar.setEvents(newEventsArray);
// Add events. Note that this triggers a re-render of the calendar.
myCalendar.addEvents(additionalEventsArray);
// Remove events. All events for which the passed in function returns true will
// be removed from the calendar.
// Note that this triggers a re-render of the calendar.
myCalendar.removeEvents(function(event){
return event.id == idToRemove;
});If you are taking advantage of the onMonthChange and onYearChange callbacks, you might want them to fire whenver you call setMonth, setYear, forward, back, etc. Just pass in an object as an argument with withCallbacks: true like this:
// month will be set to February and then onMonthChange will be fired.
myCalendar.setMonth("February", { withCallbacks: true });
// month will increment and onMonthChange, and possibly onYearChange, will be
// fired.
myCalendar.next({ withCallbacks: true });CLNDR is structured so that you don't really need anything in your template.
<% _.each(days, function(day){ %>
<div class='<%= day.classes %>'><%= day.day %></div>
<% }); %>Currently CLNDR sets the class on a day to 'calendar-day-2013-05-30' and uses it to determine the date when a user clicks on it. Thus, click events will only work if days.classes is included in your day element's class attribute as seen above.
You can pass in a render function as an option, for example:
var precompiledTemplate = myRenderingEngine.template( $('#my-template').html() );
$('#my-calendar').clndr({
render: function(data) {
return precompiledTemplate(data);
}
});where the function must return the HTML result of the rendering operation. In this case you would precompile your template elsewhere in your code, since CLNDR only cares about your template if it's going to use underscore.
If you are using your own render method, underscore.js is NOT a dependency of this plugin.
CLNDR has been tested successfully with doT.js, Hogan.js, and Handlebars.js. Please get in touch if you have success with other languages and they will be documented here.
Here's an example using doT.js...
The markup:
<script id="dot-template" type="text/template">
<div class="clndr-controls">
<div class="clndr-previous-button">‹</div>
<div class="month">{{= it.month }}</div>
<div class="clndr-next-button">›</div>
</div>
<div class="clndr-grid">
<div class="days-of-the-week">
{{~it.daysOfTheWeek :day:index}}
<div class="header-day">{{= day }}</div>
{{~}}
<div class="days">
{{~it.days :day:index}}
<div class="{{= day.classes }}">{{= day.day }}</div>
{{~}}
</div>
</div>
</div>
</script>The Javascript:
var clndrTemplate = doT.template( $('#dot-template').html() );
$('#calendar').clndr({
render: function(data) {
return clndrTemplate(data);
}
});Clndr has support for internationalization insofar as Moment.js supports it. By configuring your Moment.js instance to a different language, which you can read more about here: i18n in Moment.js, you are configuring Clndr as well.
If you are using a moment.js language configuration in which weeks begin on a Monday (e.g. French), Clndr will detect this automatically and there is no need to provide a weekOffset or a daysOfTheWeek array. If you want to reverse this behavior, there is a field in each moment.js language config file called dow which you can set to your liking.
The day of the week abbreviations are created automatically using moment.js's current language setting, however if this does not suit your needs you should override them using the daysOfTheWeek option. Make sure the array you provide begins on the same day of the week as your current language setting. Warning: using daysOfTheWeek and weekOffset in conjunction with different language settings is not recommended and may cause you headaches.
If you're not a fan of <% %> and <%= %> style delimiters you can provide Underscore.js with alternatives in the form of regular expressions. There are three delimiters...
interpolate, which outputs a string (this is <%= %> by default)
escape, for escaping HTML (this is <%- %> by default)
evaluate, for evaluating javascript (this is <% %> by default)
If you're more comfortable with Jinja2/Twig/Nunjucks style delimiters, simply call this before you instantiate your clndr:
// switch to Jinja2/Twig/Nunjucks-style delimiters
_.templateSettings = {
interpolate: /\{\{(.+?)\}\}/g,
escape: /\{\{\-(.+?)\}\}/g,
evaluate: /\{\%(.+?)\%\}/g
};If you're planning on supporting IE8 and below, you'll have to be careful about version dependencies. You'll need the jQuery 1.10.x branch for IE support, and if you're taking advantage of the constraints feature you'll need to use a version of moment.js <=2.1.0 or >=2.5.1.
v1.3.3 ~ 2015-10-22: Adds ignoreInactiveDaysInSelection option for disabling selection of inactive dates when using both trackSelectedDates and constraints.
v1.3.2 ~ 2015-10-21: Adding moment instance as a config option to use instead of global moment object.
v1.3.1 ~ 2015-10-21: Trailing comma removed to work in IE11.
v1.3.0 ~ 2015-10-13: Adds destroy and get-instance methods.
v1.2.16 ~ 2015-08-18: Resolves issue 200; nextMonth click event was firing previousMonth's event erroneously.
v1.2.15 ~ 2015-07-21: Resolves issue 185; next and previous month not working correctly with today under certain configurations.
v1.2.14 ~ 2015-07-08: Small typo fixed.
v1.2.13 ~ 2015-07-08: Bugfix patch for misnamed variable.
v1.2.12 ~ 2015-06-26: Bugfix patch for broken behavior in the selected day PR.
v1.2.11 ~ 2015-06-25: Added in support for day/month intervals instead of only one month. Added in support for tracking the selected day, optionally using touch events, added a namcespace to click/touch events, and added a properties array to each day object for accessing common attributes about the day.
v1.2.10 ~ 2015-03-11: Added a performance optimization that should make rendering multiday events slightly faster in the case that some are <= one day long. This update is backwards-compatible.
v1.2.9 ~ 2015-02-20: Fixed a bug where the daysArray was accidently introduced into the global namespace. This shouldn't have affected your world. This update is backwards-compatible.
v1.2.8 ~ 2015-02-16: Added previousMonth and nextMonth variables into the template, which match month in format, so that now in "April" you also have access to the strings "March" and "May". This update is backwards-compatible.
v1.2.7 ~ 2015-01-21: Added the ability to mix multi-day and single-day events using the new multiDayEvents.singleDay property. Also introduced lazy setting of startDate and endDate in multi-day events so that if one of them is missing they will both be set to the value that is present. This update is backwards-compatible.
v1.2.6 ~ 2015-01-07: Added the ability to specify custom classnames for event, next-month, previous-month, etc. using options.classes. This update is backwards-compatible.
v1.2.5 ~ 2014-12-01: Reverting the previous DST code change, which introduced a bug for a large number of users.
v1.2.4 ~ 2014-11-25: Fixed a bug related to DST in specific timezones that would cause duplicate dates to appear. Added removeEvents filtering function. warning! This version is buggy. Please upgrade to v1.2.5 if you are currently on this version.
v1.2.3 ~ 2014-10-15: Fixed a bug that introduced a global variable. It's possible (but very unlikely) that this might have caused some weirdness when using multiple instances of CLNDR on the same page.
v1.2.2 ~ 2014-10-01: Updated internal usage of deprecated moment.js functions.
v1.2.1 ~ 2014-07-10: Fixed a bug in eventsLastMonth, eventsThisMonth, and eventsNextMonth. Added CommonJS/AMD wrapper to the plugin.
v1.2.0 ~ 2014-01-22: BC break for Bower users! Underscore is no longer listed as a dependency in the Bower plugin, allowing you the flexibility of choosing the templating language you prefer. Also added a day of the week class to all clndr days in the format calendar-dow-<0 - 6>, allowing you to style weekends/specific days of the week differently.
v1.1.3 ~ 2014-01-17: fixed a bug where multiday events longer than two months would not show up. Fixed a bug that prevented clndr from loading in IE8.
v1.1.2 ~ 2013-12-15: using the forceSixRows option, you can now force your calendar to render six rows at all times, giving each month the same height. All classes and events come through this extra set of days just as you would expect. The usage jQuery's $.data has been corrected such that calling $(#calendar-parent-element).data('plugin_clndr') returns the clndr instance.
v1.1.1 ~ 2013-12-02: You can now only call clndr on one element at a time. If you attempt to call it on more than one element, an error is thrown. This should have no effect on previous code as long as your selectors were only returning one element. There is now a bower.json file.
v1.1.0 ~ 2013-11-04: New features! In list form:
- Multiday Events: using the
multiDayEventsoption, you can now pass in events that last more than one day. They will show up in all the days that they span across. - Constraints: you want to make a datepicker? Ok. Pass in a
constraintsoption with either astartDate,endDate, or both, and clndr will add theinactiveclass to all days that aren't within your range. When you are at the edge of the range, next and previous controls will not respond to click events & will also get the classinactive. - The use of
days.idin templates has been deprecated all the way. It will cause errors, so stop using it now please! - Public API functions (forward, back, setMonth, setYear) now accept an object with options. The only option at the moment is
withCallbacks, which if set totruewill fire theonMonthChangeandonYearChangecallbacks. - There are tests! example/test.html contains a list of human-powered tests that cover all of the basic functionality.
The only backward-compatibility break is the removal of the days.id field used within templates. Upgrading clndr should have no negative repercussions for you- please open an issue if it does and it will get fixed!
v1.0.13 ~ 2013-10-24: changed the way clndr.eventsLastMonth and clndr.eventsNextMonth propagate... previously they were only available if "showAdjacentMonths" was turned on, whereas now they are always available. They are also available in the template now as eventsLastMonth and eventsNextMonth. Fixed a bug where eventsLastMonth and eventsNextMonth were jQuery arrays instead of regular ol' Arrays. This bug was introduced in v1.0.7. cleaned up example folder.
v1.0.12 ~ 2013-10-22: you can now make next and previous year buttons using the classes clndr-next-year-button and clndr-previous-year-button, or by specifying the options targets.nextYearButton and targets.previousYearButton. doneRendering's this keyword is now set to the clndr instance. Added the ready callback, which is a good place to attach event handlers. Added clickEvents.onYearChange, which is fired whenever the year changed as a result of a click action (even if you just went to the next month and it happened to be December to January!).
v1.0.11 ~ 2013-10-19: set the context in all click events so that this now refers to your clndr instance! this is also bound to the clndr instance in the render function. Added the class past to all days before today.
v1.0.10 ~ 2013-10-16: fixed a nasty bug where events weren't getting passed into click handlers. this bug was introduced with v1.0.8! Please update.
v1.0.9 ~ 2013-10-16: Fixed an i18n bug where the days of the week would start on a Monday correctly, but the calendar grid would still start as if the first day of the week was Sunday. This fix correctly uses moment.js's current settings to determine the first day of the week. If you are planning to use CLNDR in multiple languages, update to this version!
v1.0.8 ~ 2013-10-14: Deprecated the use of days[].id, adding it instead to the list of classes. You no longer have to set an id for each day element, and if you do it will be completely ignored. Just keep using days[].classes! Fixed a bug where an adjacent month's day would show up as last-month or next-month incorrectly if the year was different. Added some validation to address a bug where ids would show up as calendar-day-Invalid Date.
v1.0.7 ~ 2013-09-30: settled on jQuery's $.filter method, opening the door to IE 7 + 8 support. If you plan on supporting IE 8 or below, don't forget to use jQuery's 1.x branch, as 2.x has dropped IE 6 - 8 support.
v1.0.6 ~ 2013-09-24: fixed a bug where daysOfTheWeek option wouldn't work.
v1.0.5 ~ 2013-09-24: added support for showing days in months adjacent to the current month, controlled using the showAdjacentMonths option. Added the ability for those adjacent days to move to their month when clicked using the adjacentDaysChangeMonth option. Added daysOfTheWeek option, which you should avoid by allowing moment.js to make the abbreviations for you. Fixed a bug where providing some targets: {} options would remove the rest of them.
v1.0.4 ~ 2013-09-14: fixed a bug in setEvents and event population where events would show up null.
v1.0.3 ~ 2013-09-14: Underscore.js is now only relied upon for its _.template() function, which means if you are using your own rendering engine you do NOT need underscore to use CLNDR.js
v1.0.0 ~ 2013-09-14: Officially v1.0.0! Added extras option, which exposes the extras variable in your template, allowing you to pass in arbitrary objects & synchronous functions for use inside of your template.
