Time formatting and parsing

Context

Go uses a reference time Mon Jan 2 15:04:05 MST 2006 to format/parse. Use time.Format and time.Parse with this layout.

Example

Format a time and parse a string.

Code example

package main

import (
    "fmt"
    "time"
)

func main() {
    t := time.Date(2025, 3, 15, 14, 30, 0, 0, time.UTC)
    fmt.Println(t.Format("2006-01-02 15:04:05"))
    fmt.Println(t.Format("Monday, 02-Jan-06 03:04 PM"))

    parsed, _ := time.Parse("2006-01-02", "2025-12-25")
    fmt.Println(parsed)
}

Output

2025-03-15 14:30:00
Saturday, 15-Mar-25 02:30 PM
2025-12-25 00:00:00 +0000 UTC
