The clock moves one hour forward in every country in the European Union, plus most other European countries. Most notably, Russia, Belarus and Iceland do not. In addition, the Crimean region of Ukraine will change to Moscow time at that point, advancing two hours. Turkey will move to Daylight Savings Time, but not until Monday morning.
Timeanddate.com has a great map illustrating the different European time zones and which ones observe DST. And if you need a little help with the time zone conversions – try their time difference calculator.
Israel, Syria, Jordan and the Palestinian territories moved their clocks forward on Friday morning, while Lebanon and Morocco advance over the weekend.
Have you ever been an hour early or late for a flight, call, meeting, etc. because you forgot about DST? For your sake, we hope not, but if you have any stories to share, tell us about them in the comments below.
