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

How to calculate number of seconds between two Instant in Java

In Java, we can use the ChronoUnit.SECONDS.between() method to calculate the number of seconds between two Instant values as the following example Java code.

SecondsBetweenInstantExample.java

import java.time.Instant;
import java.time.temporal.ChronoUnit;

public class SecondsBetweenInstantExample {
    public static void main(String... args) {
        Instant startInstant = Instant.parse("2022-08-13T12:00:00.0Z");
        Instant endInstant = Instant.parse("2022-08-13T12:02:30.0Z");

        // Calculate Number of Seconds Between two Instant
        long numberOfSeconds = ChronoUnit.SECONDS.between(startInstant, endInstant);

        System.out.println(String.format("Number of seconds between %s and %s is %d", startInstant, endInstant, numberOfSeconds));
    }
}
The output as below.
Number of seconds between 2022-08-13T12:00:00Z and 2022-08-13T12:02:30Z is 150
