ATnight from 27 to 28 March 2010   the traditional "translation of the arrows" takes place 1 hour ahead. Thus, more than one hundred states of the world annually implement the transition to summer time.

For the first time, "arrows were translated" in the UK in the distant1908. then the transition to "summer" time allowed to significantly save fuel for artificial lighting. In the former USSR, for "summer" time, for the first time,1917   year. Later, in1930   The clock was changed to "summer" time and back was canceled, instead of it was introduced the so-called maternity time, according to which the hands of the clock were translated an hour ahead of the time zone.

AT1981   year it was decided to switch back to "summer" time, however, the maternity time was not abolished at the same time. Thus and up to now, those countries of the former USSR, in which the transition to summer time is practiced, for two hours "outstrip" the standard time in summer and for an hour in winter.

The transition to summer time is annually held on the last Sunday in March   and is caused, first of all, by the economy of electric power. Specialists have calculated that with this simple method this savings reaches up to 2% of annual electricity consumption. However, the effectiveness of such savings is questionable.

First, the economy of a billion and a half kilowatt hours in the whole state in terms of per capita is less than one dollar a year. Secondly, what still managed to "save" due to the transition to "summer" time is more than returned with the transition to the "normal" time in October, because people are forced to turn on the lighting in the evening and do not turn it off in the morning.

And, thirdly, electricity costs have long been not counted only by lighting. Household appliances, such as a refrigerator, a TV, a vacuum cleaner or a washing machine, humanity uses, no matter how light or dark outside the window. In addition, in large enterprises or in administrative buildings, lighting is generally included, because the area of ​​windows compared with the total area of ​​the premises is much smaller.

In addition to doubts about the economic feasibility of "transferring arrows", the transition to "summer" time causesmedical concern. In healthy people, problems with the translation of the clock usually does not arise, but some people still experience some discomfort. In the period of adaptation of the organism to the "new" time, exacerbations of cardiovascular diseases, a decrease in working capacity, insomnia or, conversely, drowsiness, general deterioration of well-being or increased irritability are possible.

On November 12, 2009, Russian President Dmitry Medvedev in his address to the Federal Assembly of the Russian Federation said that it was necessary to consider the expediency of the transition to summer and winter time: "This applies, incidentally, to the expediency of the transition to summer and winter time. Here, too, you need to compare all the benefits of saving, obvious inconveniences, but you need to do it. " Immediately in the State Duma deputy of the faction "United Russia" Vasily Zakharyashchev was introduced a bill "On the transition of the Russian Federation to the world time." In this bill, it is also planned to abolish "maternity time".

In 2010, the translation of the hour hands forward one hour ahead will take place on March 28 at 2 am Moscow time.
