Proposal Details

With current time pkg api, what is a good way to validate if a given input date is valid or not?

Suppose a scenario we have given three ints 2021, 02 and 29, for year,month,day and need to validate if it represents a valid date or not.

This can be achieved by writing a small helper function like

func isValidDate(year, month, day int) bool {
	t := time.Date(year, time.Month(month), day, 0, 0, 0, 0, time.UTC)
	y, m, d := t.Date()

	return y == year && m == time.Month(month) && d == day
}

Or maybe another way could be -

func isValidDate(year, month, day int) bool {
	dateStr := fmt.Sprintf("%d-%d-%d", year, month, day)
	_, err := time.Parse("2006-1-2", dateStr)
	return err == nil
}

What approach would u recommend for this? Or is this use case worthy enough to be added in the time pkg?
