On the night of Saturday to Sunday, October 26-27, Romania officially switches to winter time, and the clocks will be turned back one hour so that 4 a.m. will become 3 a.m. and Sunday, October 27, will be the longest day of the year, basically having 25 hours.
Winter time is linked to the concept of astronomical hour and is normally used in most countries or territories from October to April. Winter time is called thus in contrast to summer time, the latter’s purpose being to fully use sunlight for as long as possible. As a rule, summer time is adopted each year, on the last Sunday of March (3 a.m. becomes 4 a.m.). Winter time is adopted on the last Sunday of October (4 a.m. becomes 3 a.m.).
Romania will revert to summer time on 29 March 2020.
