Remember in the UK and most of Europe, Daylight Savings Time starts on Sunday, 31 March 2019 at 01:00:00. Clocks for example in the UK are turned forward 1 hour to Sunday 31 March 2019, 02:00:00.
Turkey will now be only two hours ahead of the UK and Ireland. As you cross over Europe, this will change to one hour instead of two. Not all countries observe the time change.
