Go Persian Calendar provides functionality for conversion among Persian (Solar Hijri) and Gregorian calendars. A Julian calendar is used as an interface for all conversions. The package name is ptime and it is compatible with the package time. All months are available with both Iranian and Dari Persian names.

go get github.com/yaa110/go-persian-calendar1- Import the package ptime. Most of the time you need to import time and fmt packages, too.
import (
ptime "github.com/yaa110/go-persian-calendar"
"time"
"fmt"
)2- Convert Gregorian calendar to Persian calendar.
// Create a new instance of time.Time
var t time.Time = time.Date(2016, time.January, 1, 12, 1, 1, 0, ptime.Iran())
// Get a new instance of ptime.Time using time.Time
pt := ptime.New(t)
// Get the date in Persian calendar
fmt.Println(pt.Date()) // output: 1394 دی 113- Convert Persian calendar to Gregorian calendar.
// Create a new instance of ptime.Time
var pt ptime.Time = ptime.Date(1394, ptime.Mehr, 2, 12, 59, 59, 0, ptime.Iran())
// Get a new instance of time.Time
t := pt.Time()
// Get the date in Gregorian calendar
fmt.Println(t.Date()) // output: 2015 September 244- Get the current time.
// Get a new instance of ptime.Time representing the current time
pt := ptime.Now()
// Get year, month, day
fmt.Println(pt.Date()) // output: 1394 بهمن 11
