⏳ Time difference between two dates in Go

To calculate the time difference between two dates, e.g., years, months, weeks, days, hours, minutes, seconds, milliseconds, microseconds, nanoseconds between one date and the other, use the Sub() method on the time.Time struct. It calculates the difference between the two dates. Then using the built-in methods, you can determine the specific number of hours, minutes, seconds, etc., that have passed in that difference.

package main

import (

func main() {
    firstDate := time.Date(2022, 4, 13, 1, 0, 0, 0, time.UTC)
    secondDate := time.Date(2021, 2, 12, 5, 0, 0, 0, time.UTC)
    difference := firstDate.Sub(secondDate)

    fmt.Printf("Years: %d\n", int64(difference.Hours()/24/365))
    fmt.Printf("Months: %d\n", int64(difference.Hours()/24/30))
    fmt.Printf("Weeks: %d\n", int64(difference.Hours()/24/7))
    fmt.Printf("Days: %d\n", int64(difference.Hours()/24))
    fmt.Printf("Hours: %.f\n", difference.Hours())
    fmt.Printf("Minutes: %.f\n", difference.Minutes())
    fmt.Printf("Seconds: %.f\n", difference.Seconds())
    fmt.Printf("Milliseconds: %d\n", difference.Milliseconds())
    fmt.Printf("Microseconds: %d\n", difference.Microseconds())
    fmt.Printf("Nanoseconds: %d\n", difference.Nanoseconds())

There are no built-in methods for calculating the number of days, weeks, months, or years between two dates. You have to do it manually using the Duration.Hours() method.


Years: 1
Months: 14
Weeks: 60
Days: 424
Hours: 10196

Microseconds: 36705600000000
