Ukraine switched to summer time. The hands of the clock were moved an hour forward at 3:00 on Sunday, March 25.
This annual procedure is carried out to save energy consumption. However, the transition to another time regime leads to a deterioration of sleep, the work of the cardiovascular and immune systems, as well as other metabolic processes.
Removing the hands of the clock for summer time on the territory of Ukraine is carried out every year since 1981. It is believed that this leads to more efficient use of daylight hours during the summer.
Earlier it was stipulated that in 2012 the clock hands in Ukraine will be moved for the last time. But the Ukrainian authorities did not consider this issue, so the process of moving the clock twice a year remained a tradition of the country.
The transition to seasonal time is carried out in more than one hundred countries of the world. In particular, the US and Canada have already switched to summer time. All the countries of the world that operate on such a system move the hands of the clock on different days. In Jordan, the clock is moved according to the scheme "last Thursday in March - the last Friday of September", and in Brazil - "the third Sunday in February - the third Sunday in October." In addition, many agrarian countries refused to switch to "summer" time, because the working day there provides the highest efficiency during the daytime.
In Europe, only Iceland, Belarus and Russia do not switch to summer time. In the post-Soviet space the watch hands are moved only in Ukraine and Moldova. Earlier in 2011, the Russian Federation decided not to switch to winter time. But the last country that refused this was Turkey.
