Create an ICS file from Facebook birthdays

I couldn't get other solutions to work because of two-factor-authentication and trust issues. So I wrote this script to remember my friends' birthdays. The ICS file can be imported in common calendar applications. It is written in simplest Python and does not perform any network communication, perfect for people with trust issues.

I tried it with English (US) and German locale setting on Facebook, may work for others as well.

Instructions

Clone repo or just download Python script
Visit https://www.facebook.com/events/birthdays/
Scroll to bottom of page (so that all Facebook birthdays have been loaded)
Export HTML of page (see next chapter)
Run python3 facebook_birthday_parser.py <PATH TO YOUR HTML EXPORT>
Import birthdays.ics in your favorite calendar application

Export HTML

Kinda tricky, because a simple Ctrl+S usually does not help. We need the dynamically loaded content as well, and Ctrl+S does not save the Javascript generated content.

Option 1: Use a small Javascript

Full javascript:

function download() {
    var f = new Blob([document.documentElement.innerHTML], {type: "text/html"});
    if (window.navigator.msSaveOrOpenBlob) {
        window.navigator.msSaveOrOpenBlob(f, "birthdays.html");
    } else {
        var a = document.createElement("a"), u = URL.createObjectURL(f);
        a.href = u;
        a.download = "birthdays.html";
        a.click();
    }
}

Ready to copy: javascript: var f = new Blob([document.documentElement.innerHTML], {type: "text/html"}); if (window.navigator.msSaveOrOpenBlob) { window.navigator.msSaveOrOpenBlob(f, "birthdays.html"); } else { var a = document.createElement("a"), u = URL.createObjectURL(f); a.href = u; a.download = "birthdays.html"; a.click();

Paste it in your browser's URL line. Works at least for me in Chrome, but not in newer Firefoxes.

Option 2: Use the developer console

Chrome: Ctrl + Shift + J Firefox: Ctrl + Shift + I

Right click on <html ...
Copy
Outer HTML
Paste it into a file

or use the above Javascript code in the console tab: var f = new Blob([document.documentElement.innerHTML], {type: "text/html"}); if (window.navigator.msSaveOrOpenBlob) { window.navigator.msSaveOrOpenBlob(f, "birthdays.html"); } else { var a = document.createElement("a"), url = URL.createObjectURL(f); a.href = url; a.download = "birthdays.html"; a.click();

It may work, it may not. Do not trust this tool and better check Facebook before congratulating your friends. ;)
