Comparing two dates in Golang

Problem Solution:

In this program, we will create three objects of time structure and then we will compare objects using the "==" operator and print the appropriate message on the console screen.

Program/Source Code:

The source code to compare the two dates is given below. The given program is compiled and executed successfully.

Golang code to compare two dates

// Golang program to compare two dates

package main

import "fmt"
import "time"

func main() {
	date1 := time.Date(2021, 3, 20, 10, 5, 20, 0, time.UTC)
	date2 := time.Date(2021, 3, 20, 10, 5, 20, 0, time.UTC)
	date3 := time.Date(2020, 3, 20, 10, 5, 20, 0, time.UTC)

	if date1 == date2 {
		fmt.Println("date1 is equal to date2")
	} else {
		fmt.Println("date1 is not equal to date2")
	}

	if date1 == date3 {
		fmt.Println("date1 is equal to date3")
	} else {
		fmt.Println("date1 is not equal to date3")
	}
}

Output:

date1 is equal to date2
date1 is not equal to date3

Explanation:

In the above program, we declare the package main. The main package is used to tell the Go language compiler that the package must be compiled and produced the executable file. Here, we imported the fmt and time packages to use time and fmt related functions.

In the main() function, we created three objects of time structure date1, date2, date3 initialized using Date() function. After that, we used the "==" operator to compare dates and print the appropriate message on the console screen.
