This Go tutorial help to understand time package of golang. Go provides extensive support for times and duration.Time package have many builtin function that help to solve daily common programming issues, which was other programming language do not have.

then := time.Date(2016, 06, 12, 24, 46, 37, 4355433, time.UTC)
fmt.Println("Then time in UTC FORMAT is :", then)

How to get Year, Month and Day

fmt.Println("Then year is :", then.Year())
fmt.Println("Then Month is :", then.Month())
fmt.Println("Then Day is :", then.Day())
fmt.Println("Then Weekday is :", then.Weekday())

diff := now.Sub(then)
fmt.Println("Difference in hour :", diff.Hours())
fmt.Println("Difference in day :", diff.Hours())
fmt.Println("Number of days :", int(diff.Hours()/24))
