Java TimeZone inDaylightTime() Method
Description
The Java TimeZone inDaylightTime(Date date) method is used to query if the given date is in daylight savings time in this time zone.
Declaration
Following is the declaration for java.util.TimeZone.inDaylightTime() method.
public abstract boolean inDaylightTime(Date date)
Parameters
date − This is the given Date
Return Value
The method call returns true if the given date is in daylight savings time, false, otherwise.
Exception
NA
Checking a GMT TimeZone to be in DayLight Saving Time Example
The following example shows the usage of Java TimeZone inDaylightTime(Date) method to check if a given date is in daylight saving time. We've created a TimeZone using GMT and a date using Date object with current time. Then we've checked date being in daylight savings using inDaylightTime() ethod and printed the status.
package com.tutorialspoint; import java.time.Instant; import java.util.Date; import java.util.TimeZone; public class TimeZoneDemo { public static void main( String args[] ) { // create simple time zone object TimeZone stobj1 = new SimpleTimeZone(820,"GMT"); // create date Date date = Date.from(Instant.now()); // check day light boolean daylight = stobj1.inDaylightTime(date); // checking the value of day light System.out.println("Is in day light : " + daylight); } }
Output
Let us compile and run the above program, this will produce the following result.
Is in day light : false
Checking a US TimeZone to be in DayLight Saving Time Example
The following example shows the usage of Java TimeZone inDaylightTime(Date) method to check if a given date is in daylight saving time. We've created a TimeZone using US and a date using Date object with current time. Then we've checked date being in daylight savings using inDaylightTime() ethod and printed the status.
package com.tutorialspoint; import java.time.Instant; import java.util.Date; import java.util.TimeZone; public class TimeZoneDemo { public static void main( String args[] ) { // create simple time zone object TimeZone stobj1 = new SimpleTimeZone(820,"US"); // create date Date date = Date.from(Instant.now()); // check day light boolean daylight = stobj1.inDaylightTime(date); // checking the value of day light System.out.println("Is in day light : " + daylight); } }
Output
Let us compile and run the above program, this will produce the following result.
Is in day light : false
Checking a BST TimeZone to be in DayLight Saving Time Example
The following example shows the usage of Java TimeZone inDaylightTime(Date) method to check if a given date is in daylight saving time. We've created a TimeZone using BST and a date using Date object with current time. Then we've checked date being in daylight savings using inDaylightTime() ethod and printed the status.
package com.tutorialspoint; import java.time.Instant; import java.util.Date; import java.util.TimeZone; public class TimeZoneDemo { public static void main( String args[] ) { // create simple time zone object TimeZone stobj1 = new TimeZone(820,"BST"); // create date Date date = Date.from(Instant.now()); // check day light boolean daylight = stobj1.inDaylightTime(date); // checking the value of day light System.out.println("Is in day light : " + daylight); } }
Output
Let us compile and run the above program, this will produce the following result.
Is in day light : false
