Java ZonedDateTime getZone()

In this guide, you will learn about the ZonedDateTime getZone() method in Java programming and how to use it with an example.

1. ZonedDateTime getZone() Method Overview


The getZone() method of the ZonedDateTime class in Java is used to get the ZoneId of this ZonedDateTime. A ZoneId represents a time-zone identifier and provides rules for converting between an Instant and a LocalDateTime.


ZoneId getZone()


The method does not take any parameters.

Key Points:

- The getZone() method returns the ZoneId associated with this ZonedDateTime.

- A ZoneId is used to identify the rules used to convert an Instant to a LocalDateTime.

- Every ZonedDateTime is associated with a ZoneId that specifies the time-zone rules.

2. ZonedDateTime getZone() Method Example

import java.time.ZoneId;
import java.time.ZonedDateTime;

public class ZonedDateTimeGetZoneExample {
    public static void main(String[] args) {
        // Creating a ZonedDateTime instance with the time-zone of Europe/Paris
        ZonedDateTime zonedDateTime = ZonedDateTime.of(2023, 9, 20, 12, 34, 56, 0, ZoneId.of("Europe/Paris"));
        System.out.println("ZonedDateTime: " + zonedDateTime);

        // Getting the ZoneId of this ZonedDateTime
        ZoneId zoneId = zonedDateTime.getZone();
        System.out.println("ZoneId: " + zoneId);

        // Getting ZoneId of a ZonedDateTime with system default time-zone
        ZonedDateTime systemDefaultZonedDateTime =;
        ZoneId defaultZoneId = systemDefaultZonedDateTime.getZone();
        System.out.println("System Default ZoneId: " + defaultZoneId);


ZonedDateTime: 2023-09-20T12:34:56+02:00[Europe/Paris]
ZoneId: Europe/Paris
System Default ZoneId: 


In this example, a ZonedDateTime instance was created with a specific time zone of Europe/Paris. 

The getZone() method was then called to retrieve the ZoneId associated with this ZonedDateTime, which returned Europe/Paris. Additionally, the getZone() method was used to get the ZoneId of a ZonedDateTime created with the system's default time zone. 

The actual output for the system default ZoneId will depend on the system configuration where the code is run.
