To get the difference between two times in hours,

2. Use the Hours() method to get difference time in hours.

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

Let’s start today’s tutorial How do I get difference between two times in hours 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 to get the difference in hours.

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 hours
    fmt.Printf("Hours: %f\n", diff.Hours())
}

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

Try it yourself

All the best 👍
