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.
Will Greece be one of the countries that still changes the clocks after tonight?
The Commission proposal to scrap clock changes completely in the EU from 2021 was approved by the EU Parliament but I cannot find out if it was ratified by the Council yet. If it is ratified then ALL EU countries are supposed to stop clock changes in 2021 BUT they can choose whether to be on winter time or summer time permanently. For those who opt to stay on summertime the change forward last night should be the last time they change. For those who opt to stay on winter time they should change their clocks back in October. I don’t know what Greece is opting to do and I don’t even know if it will happen as I describe but that is supposed to be the plan.
Logically countries should opt for summertime. Optimum use of daylight is achieved if our waking day is equally distributed about solar noon. Typically our waking day is not equally distributed about clock noon but we are awake longer after clock noon than before it. That means clock noon should be forward of solar noon. Winter time aligns clock and solar noon. Summer time moves clock noon forward of solar noon.
you will be surprised how many countries in the European North want to keep weinter time only
No, I’m not really surprised. It seems to be countries that have the biggest difference in day length through the year, i.e. more northerly, that prefer to keep the clock change and if they are forced to scrap it then they prefer winter time. Even in the UK the argument is strongest from Scotland rather than the south of England. Countries with the shortest difference in day length through the year, i.e. Mediterranean ones, tend to be happier scrapping the clock change and adopting either winter time or summer time.
