go - How to parse only date to time.Time? -

i want parse date value time.time. example have date in format: 2016-03-31, , want parse it, like: time.parse(format, "2016-03-31").

but fail.

what correct format string use parse date format?

i have code below example, on playground also: https://play.golang.org/p/0mnlr9emzd

package main  import (     "fmt"     "time" )  var datetoparse = "2016-03-31"  func main() {     format := "2006-12-01"     parsedate(format) }  func parsedate(format string) {     t, err := time.parse(format, datetoparse)     if err != nil {         fmt.println("format:", format)         fmt.println(err)         fmt.println("")         return     }     fmt.println("works format:", format)     fmt.println(t)     fmt.println("") } 

the output this:

format: 2006-12-01 parsing time "2016-03-31" "2006-12-01": cannot parse "-31" "2" 

package time

these predefined layouts use in time.format , time.parse. reference time used in layouts specific time:

mon jan 2 15:04:05 mst 2006 

which unix time 1136239445. since mst gmt-0700, reference time can thought of as

01/02 03:04:05pm '06 -0700 

to define own format, write down reference time formatted way; see values of constants ansic, stampmicro or kitchen examples.

use format := "2006-01-02" yyyy-mm-dd.
