Golang : Get today's weekday name and calculate target day distance example


Tags : golang weekday monday-friday switch-case

Let's calculate how long it will take to reach Friday from today using switch evaluation. The code sample below will get today's weekday and evaluate the sum of today + n (n is the number of days) before hitting Friday.

 package main

 import (
 "fmt"
 "time"
 )

 func main() {

 today := time.Now().Weekday()
 fmt.Println("Today is ", today)

 fmt.Println("When's Friday?")
 switch time.Friday {
 case today + 0:
 fmt.Println("Today.")
 case today + 1:
 fmt.Println("Tomorrow.")
 case today + 2:
 fmt.Println("In two days.")
 case today + 3:
 fmt.Println("In three days.")
 case today + 4:
 fmt.Println("In four days.")
 case today + 5:
 fmt.Println("In five days.")
 default:
 fmt.Println("Will be sometime away.")
 }
 }

Sample output :

Today is Monday

When's Friday?

In four days.
