In this Java core tutorial we learn how to calculate number of days between two LocalDateTime values using the java.time.temporal.ChronoUnit class in Java programming language.

How to get number of days between two LocalDateTime in Java

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

BetweenLocalDateTimeExample.java

import java.time.LocalDateTime;
import java.time.temporal.ChronoUnit;

public class BetweenLocalDateTimeExample {
    public static void main(String... args) {
        LocalDateTime start = LocalDateTime.parse("2020-08-10T08:30:00");
        LocalDateTime end = LocalDateTime.parse("2022-08-30T23:50:00");

        // Calculate Number of Days Between LocalDateTime
        long numberOfDays = ChronoUnit.DAYS.between(start, end);

        System.out.println(String.format("Number of days between %s and %s is %d", start, end, numberOfDays));
    }
}
The output as below.
Number of days between 2020-08-10T08:30 and 2022-08-30T23:50 is 750
