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

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 get the last day of this month. Something like this:

package main

import (

func main() {

    date := time.Now()
    nextMonth := date.Add(time.Month)
    LastDay := nextMonth.Add(-time.Hour * 24)
