ZonedDateTime minusDays() method in Java with Examples Last Updated : 10 Dec, 2018 Comments Improve Suggest changes Like Article Like Report minusDays() method of a ZonedDateTime class used to subtract the number of specified days from this ZonedDateTime and return a copy of ZonedDateTime.This method subtracts no of days passed as a parameter from the local date-time and then it is converted back to a ZonedDateTime, using the zone ID to obtain the offset. When converting back to ZonedDateTime, if the local date-time is in an overlap, then the offset will be retained if possible, otherwise, the earlier offset will be used. This instance is immutable and unaffected by this method call. Syntax: public ZonedDateTime minusDays(long days) Parameters: This method accepts a single parameter days which represents the days to subtract, It can be negative. Return value: This method returns a ZonedDateTime based on this date-time with the days subtracted. Exception: This method throws DateTimeException if the result exceeds the supported date range. Below programs illustrate the minusDays() method: Program 1: Java // Java program to demonstrate // ZonedDateTime.minusDays() method import java.time.*; public class GFG { public static void main(String[] args) { // create a ZonedDateTime object ZonedDateTime zoneddatetime = ZonedDateTime.parse( "2018-12-06T19:21:12.123+05:30[Asia/Calcutta]"); // print instance System.out.println("ZonedDateTime before" + " subtracting days: " + zoneddatetime); // subtract 13 days ZonedDateTime returnvalue = zoneddatetime.minusDays(13); // print result System.out.println("ZonedDateTime after " + " subtracting 13 days: " + returnvalue); } } Output: ZonedDateTime before subtracting days: 2018-12-06T19:21:12.123+05:30[Asia/Calcutta] ZonedDateTime after subtracting 13 days: 2018-11-23T19:21:12.123+05:30[Asia/Calcutta] Program 2: Java // Java program to demonstrate // ZonedDateTime.minusDays() method import java.time.*; public class GFG { public static void main(String[] args) { // create a ZonedDateTime object ZonedDateTime zoneddatetime = ZonedDateTime.parse( "2018-10-25T23:12:31.123+02:00[Europe/Paris]"); // print instance System.out.println("ZonedDateTime before" + " subtracting days: " + zoneddatetime); // subtract 22 days ZonedDateTime returnvalue = zoneddatetime.minusDays(20); // print result System.out.println("ZonedDateTime after " + " subtracting 24 days: " + returnvalue); } } Output: ZonedDateTime before subtracting days: 2018-10-25T23:12:31.123+02:00[Europe/Paris] ZonedDateTime after subtracting 24 days: 2018-10-05T23:12:31.123+02:00[Europe/Paris] Reference: https://docs.oracle.com/javase/10/docs/api/java/time/ZonedDateTime.html#minusDays(long).html#minusYears(long) Comment More infoAdvertise with us Next Article ZonedDateTime minusDays() method in Java with Examples A AmanSingh2210 Follow Improve Article Tags : Java Java-Functions Java-time package Java-ZonedDateTime Practice Tags : Java Similar Reads ZonedDateTime plusDays() method in Java with Examples The plusDays() method of ZonedDateTime class in Java is used to add the number of specified days in this ZonedDateTime instance and return a copy of ZonedDateTime.
