Java Calculate Number of Months Between two ZonedDateTime

Tags: Java ZonedDateTime ChronoUnit Java 8

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

How to get number of months between two ZonedDateTime in Java

In Java, we can use the ChronoUnit.MONTHS.between() method to calculate the number of months between two ZonedDateTime values as the following example Java code.

MonthsBetweenZonedDateTimeExample.java 

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

public class MonthsBetweenZonedDateTimeExample {
    public static void main(String... args) {
        ZonedDateTime startZonedDateTime = ZonedDateTime.parse("2021-08-15T08:15:30+10:00[Australia/Sydney]");
        ZonedDateTime endZonedDateTime = ZonedDateTime.parse("2022-08-15T08:15:30+10:00[Australia/Sydney]");

        // Calculate Number of Months Between two ZonedDateTime
        long numberOfMonths = ChronoUnit.MONTHS.between(startZonedDateTime, endZonedDateTime);

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

    }
}
The output as below. 
Number of months between 2021-08-15T08:15:30+10:00[Australia/Sydney] and 2022-08-15T08:15:30+10:00[Australia/Sydney] is 12
