Get the first and last day of current month in Go/Golang?

Question

I\'m trying to get the first and last day of the current month. You can add days and hours but not the month, which I was thinking of subtracting one day from the next month to

Answer 1

Not sure when AddDate(...) was added to time.Time, but quite possibly it was added after this question had its prime time :)

Here's another way to achieving the same with time.Time.AddDate(...) -

func BeginningOfMonth(date time.Time)  (time.Time) {
    return date.AddDate(0, 0, -date.Day() + 1)
}

func EndOfMonth(date time.Time) (time.Time) {
    return date.AddDate(0, 1, -date.Day())
}

Then you could use today := time.Now() and pass it over to one/both of the functions like so - eom := EndOfMonth(today) to get the appropriate date.

If time, DST and such are important, it should be pretty straightforward to ornament those details on top of it once you get the date.

Finally, here's a playground link where you can play around with it - https://play.golang.org/p/DxnGuqh6g4k
