How to calculate time difference between two time zones in Java

Chapter: Date and Time Last Updated: 20-09-2023 14:43:52 UTC

Program:

            /* ............... START ............... */
                

import java.time.ZoneId;
import java.time.ZonedDateTime;
import java.time.Duration;

public class TimeZoneDifference {
    public static void main(String[] args) {
        // Define two time zones
        ZoneId zone1 = ZoneId.of("America/New_York"); // Example: New York
        ZoneId zone2 = ZoneId.of("Europe/London");   // Example: London

        // Get the current time in both time zones
        ZonedDateTime currentTimeZone1 = ZonedDateTime.now(zone1);
        ZonedDateTime currentTimeZone2 = ZonedDateTime.now(zone2);

        // Calculate the time difference
        Duration timeDifference = Duration.between(currentTimeZone1, currentTimeZone2);

        // Print the time difference
        System.out.println("Time difference between " + zone1 + " and " + zone2 + " is " +
             timeDifference.toHours() + " hours");
    }
}

                /* ............... END ............... */
        

Output

Time difference between America/New_York and Europe/London is 5 hours

Notes:

  • First We import the necessary classes from the java.time package.
  • Then We define two ZoneId objects, representing the time zones you want to compare (in this case, New York and London).
  • Next step get the current time in both time zones using ZonedDateTime.now().
  • Then we calculate the time difference between the two ZonedDateTime objects using Duration.between().
  • Finally, we print out the time difference in hours using timeDifference.toHours().
  • Make sure to replace "America/New_York" and "Europe/London" with the desired time zones for your specific use case.
