Java Calculate Number of Hours Between two OffsetDateTime

Tags: Java OffsetDateTime ChronoUnit Java 8

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

How to get number of hours between two OffsetDateTime in Java

In Java, we can use the ChronoUnit.HOURS.between() method to calculate the number of hours between two OffsetDateTime values as the example Java code below.

HoursBetweenOffsetDateTimeExample.java

import java.time.OffsetDateTime;
import java.time.temporal.ChronoUnit;

public class HoursBetweenOffsetDateTimeExample {
    public static void main(String... args) {
        OffsetDateTime startOffsetDateTime = OffsetDateTime.parse("2022-08-14T07:00:00.00+07:00");
        OffsetDateTime endOffsetDateTime = OffsetDateTime.parse("2022-08-14T13:00:00.00+07:00");

        // Calculate Number of Hours Between two OffsetDateTime
        long numberOfHours = ChronoUnit.HOURS.between(startOffsetDateTime, endOffsetDateTime);

        System.out.println(String.format("Number of hours between %s and %s is %d",
                startOffsetDateTime,
                endOffsetDateTime,
                numberOfHours));
    }
}
The output as below.
Number of hours between 2022-08-14T07:00+07:00 and 2022-08-14T13:00+07:00 is 6
