2024 Clock Change Ukraine. That starts the clock for countries to produce new nationally determined contributions plans with 2035 targets that are aligned with the 1.5 degree goal. Ukraine will be the next country making the final switch to permanent winter time later in 2024.
In the early hours of october 30, ukraine switched to winter daylight saving time by turning the clocks one hour backwards. So always in the night of the last sunday in march and october.
