Clocks in Greece will turn one hour ahead for daylight savings time at 3 a.m. on Sunday morning. Clocks should be set at 4 a.m.
Daylight savings time always goes into effect on the last Sunday of March, to change back on the last Sunday of October, when Greeks switch clocks one hour back.
In March 2019, the European Parliament backed a proposal to abolish the clock-changing practice in 2021.
Daylight Saving Time occurs in most US states and territories except Arizona, Hawaii, Puerto Rico, the Virgin Islands, American Samoa, Guam, and the Northern Mariana Island.
This year, participating US states began Daylight Saving Time at 2 a.m on. Sunday, March 8.
