In this Java tutorial, we learn how to add a number of days into current ZonedDateTime value in Java programming language.

How to add number of days to current ZonedDateTime in Java

We can follow these steps to add number of days into current ZonedDateTime value.

  • Instantiate the current ZonedDateTime object using the ZonedDateTime.now() static method.
  • Use the ZonedDateTime.plusDays(long days) method to create new ZonedDateTime object with number of days added.

AddDaysToCurrentZonedDateTimeExample.java 

import java.time.ZonedDateTime;

public class AddDaysToCurrentZonedDateTimeExample {
    public static void main(String... args) {
        int numberOfDays = 20;

        // Add Number of Days to Current ZonedDateTime
        ZonedDateTime currentZoneDateTime = ZonedDateTime.now();
        ZonedDateTime newZonedDateTime = currentZoneDateTime.plusDays(numberOfDays);

        System.out.println("Number of days: " + numberOfDays);
        System.out.println("Current ZonedDateTime: " + currentZoneDateTime);
        System.out.println("New ZonedDateTime: " + newZonedDateTime);
    }
}
The output as below. 
Number of days: 20
Current ZonedDateTime: 2022-09-07T20:28:16.162535700+07:00[Asia/Bangkok]
New ZonedDateTime: 2022-09-27T20:28:16.162535700+07:00[Asia/Bangkok]
