Ukraine switched to daylight saving time (DST), so-called summer time, on March 31. The clocks were set one hour ahead at 3:00 AM.
On October 28, 2018 night Ukraine switched to winter time and turned the clocks one hour back.
The UK invented those clock changes to summer time or to winter time for saving electricity in 1908. The Soviet Union switched the time for the first time in 1981.
The summer time is set in more than 70 countries, in particular, almost every EU country. On August 2018 the European Parliament has backed a proposal to stop the obligatory one-hour clock change. On March 26, 2019, the MEPs voted for the proposal, which requires states to stop the twice-yearly clock change from 2021, and choose either permanent summer time or winter time.
In Europe, only Iceland, Belarus, and Russia do not switch to winter time. In the post-Soviet space, the watch hands are moved only in Ukraine and Moldova. The Russian Federation decided not to switch to winter time in 2011, Ukraine decided no switch as well, but later this decision was canceled.
