At 2 o’clock, Friday morning Israel time, the clocks in the holy land will be moved forward one hour and the time will be 3 AM.
The summer clock period will last 193 days and will end on Sunday, October 6. This means that the high holidays and Succot in Israel this year will be kept on the summer clock.
Daylight saving time (DST) is kept mostly in North American and European countries, but not in most of Asia and Africa. Russia, China and Iceland have been keeping the summer clock year round. DST does not have much practical effect in extremely northern or southern locations, because the very long/short days mean that the artificial manipulation of time has little or no real impact on daily life, since sunrise/sunset times are already dramatically out of synch with modern working hours. DST is also of no use for locations near the equator, because they see only a very small variation in daylight through the year.
It is recommended to change all the clocks in one’s house at one time, and to use this opportunity to change the batteries.
