Ukraine has observed daylight saving time since 1981 (then part of the Soviet Union) switching to EEST on the last Sunday in March at 03:00 local time, and switching to EET on the last Sunday in October at 04:00 local time.
In 2020, the Verkhovna Rada of Ukraine submitted a draft law dated 09.10.2020 "On the calculation of time in Ukraine", which provides for the rejection of the seasonal transition of time from 2021.[1]
