Java Calculate Number of Days Between two OffsetDateTime

Tags: Java OffsetDateTime ChronoUnit Java 8

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

How to get number of days between two OffsetDateTime in Java

In Java, we can use the ChronoUnit.DAYS.between() method to calculate the number of days between two OffsetDateTime values as the following example Java program.

DaysBetweenOffsetDateTimeExample.java

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

public class DaysBetweenOffsetDateTimeExample {
    public static void main(String... args) {
        OffsetDateTime startOffsetDateTime = OffsetDateTime.parse("2022-07-01T07:00:00.00+07:00");
        OffsetDateTime endOffsetDateTime = OffsetDateTime.parse("2022-08-13T07:00:00.00+07:00");

        // Calculate Number of Days Between two OffsetDateTime
        long numberOfDays = ChronoUnit.DAYS.between(startOffsetDateTime, endOffsetDateTime);

        System.out.println(String.format("Number of days between %s and %s is %d",
                startOffsetDateTime,
                endOffsetDateTime,
                numberOfDays));
    }
}
The output as below.
Number of days between 2022-07-01T07:00+07:00 and 2022-08-13T07:00+07:00 is 43
