Calculate With Local Dates
Local dates can be used for various calendar calculations of based on
granularity days.
Since Java 8
import java.time.DayOfWeek;
import java.time.LocalDate;
import java.time.temporal.ChronoUnit;
import java.time.temporal.TemporalAdjusters;
public class CalculateWithLocalDates {
public static void main(String... args) {
LocalDate arrival = LocalDate.of(2021, 12, 28);
LocalDate departure = LocalDate.of(2022, 1, 2);
System.out.println("Nights: " + arrival.until(departure, ChronoUnit.DAYS));
arrival.datesUntil(departure).map("Dinner: %ta %<s"::formatted).forEach(System.out::println);
departure = departure.plus(3, ChronoUnit.DAYS);
System.out.printf("Stay 3 more days: %ta %<s%n", departure);
departure = departure.with(TemporalAdjusters.next(DayOfWeek.SUNDAY));
System.out.printf("Stay to next sunday: %ta %<s%n", departure);
}
