Hi Friends 👋,

Welcome To aGuideHub! ❤️

To get the difference between two times in days,

1. subtract times using the time Sub() method.
2. Use the Hours() method to get difference time in hours and divide it by / 24.

Today, I’m going to show you how do you get the difference between two times in days in golang, here we will use the golang time.Sub() method to subtract time, and time.Hours() to get the difference in days.

Let’s start today’s tutorial How do I get difference between two times in days in golang?

Here, we are going to do,

1. Define two date times object.
2. Use Sub() to get difference time.
3. Use the Hours() method and divide it by / 24 to get the difference in days.

package main

import (
    "fmt"
    "time"
)

func main() {
    currentTime := time.Now()
    oldTime := time.Date(2020, 1, 2, 0, 0, 0, 0, time.UTC)
    diff := currentTime.Sub(oldTime)

    //In Days
    fmt.Printf("Days: %f\n", diff.Hours() / 24)
}

The above program will print a number of days between two dates in the golang console, let’s check the output.

Try it yourself

All the best 👍
