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

How to get number of weeks between two LocalDate in Java

In Java, we can use the ChronoUnit.WEEKS.between() method to calculate the number of weeks between two LocalDate values as the following example Java code.

WeeksBetweenLocalDateExample.java 

import java.time.LocalDate;
import java.time.temporal.ChronoUnit;

public class WeeksBetweenLocalDateExample {
    public static void main(String... args) {
        LocalDate start = LocalDate.of(2022, 7, 1);
        LocalDate end = LocalDate.of(2022, 8, 20);

        // Calculate Number of Weeks Between two LocalDate
        long numberOfWeeks = ChronoUnit.WEEKS.between(start, end);

        System.out.println(String.format("Number of weeks between %s and %s is %d", start, end, numberOfWeeks));
    }
}
The output as below. 
Number of weeks between 2022-07-01 and 2022-08-20 is 7
