Java Calculate Number of Decades Between two ZonedDateTime

Tags: Java ZonedDateTime ChronoUnit Java 8

In this Java core tutorial, we learn how to calculate the number of decades between two ZonedDateTime objects using the java.time.temporal.ChronoUnit class in Java programming language.

How to get number of decades between two ZonedDateTime in Java

In Java, to calculate the number of decades between given start and end ZonedDateTime values we can use the ChronoUnit.DECADES.between() method as the following example Java code.

DecadesBetweenZonedDateTimeExample.java

import java.time.ZonedDateTime;
import java.time.temporal.ChronoUnit;

public class DecadesBetweenZonedDateTimeExample {
    public static void main(String... args) {
        ZonedDateTime startZonedDateTime = ZonedDateTime.parse("2000-08-15T08:15:30+10:00[Australia/Sydney]");
        ZonedDateTime endZonedDateTime = ZonedDateTime.parse("2022-08-15T08:15:30+10:00[Australia/Sydney]");

        // Calculate Number of Decades Between two ZonedDateTime
        long numberOfDecades = ChronoUnit.DECADES.between(startZonedDateTime, endZonedDateTime);

        System.out.println(String.format("Number of decades between %s and %s is %d",
                startZonedDateTime,
                endZonedDateTime,
                numberOfDecades));

    }
}
The output as below.
Number of decades between 2000-08-15T08:15:30+10:00[Australia/Sydney] and 2022-08-15T08:15:30+10:00[Australia/Sydney] is 2
