Clocks in Greece will be set forward in the early morning Sunday, March 28, 2021. The one hour change form winter to summertime will take place at 3 a.m. and digital clocks will show 4 a.m.
If you happen to have an old clock you have to do the change manually.
In 2019, the European parliament voted to scrap the twice-a-year custom of changing the clocks by an hour in spring and autumn by 2021. It has left it to national governments to decide whether to follow through.
For those countries that have decided to scrap the change twice a year, this is the last time they change.
