Jerusalem, Israel operates Daylight-Saving Time which is 3 hours ahead of Greenwich MeanTime (GMT+3). According to the Office of the Secretary General of theMinistry of Interior, there is no set rule for Daylight-saving timechanges. One thing that is entrenched in law is that there must beat least 150 days of Daylight-Saving Time annually.
At that time the clock will be moved forward one hour,from 2:00 a.m. to 3:00 a.m.
Daylight Saving Time is enforced in areas where there is a greatdifference between daylight hours in summer and in winter. In Jerusalem, Israel, forexample, there are 10 hours of daylight in winter and over 14 hours of daylightin the summer. In countries where there is such a difference, Daylight SavingTime is enforced and the result is more daylight hours during waking hours.
Near the equator, daytime and night-time are nearly the samelength (12 hours); therefore, Daylight Saving Time is not helpful and there isno point in using it.
Savings in Energy – Daylight Saving Time gives us an additionalhour of daylight in our waking hours. That is, one hour less a day to uselighting.
Maximum use of the workday
Daylight Saving Time causes people to change their sleepinghours so that they rise closer to sunrise and make better use of their workinghours.
Due to Daylight Saving Time most heavy traffic will be duringdaylight hours. As the danger of accidents is greater during darkness, it issafe to assume that Daylight Saving Time will reduce traffic accidents.
There has been a long running debate around Daylight Saving Timein Jerusalem, Israel. The main reason is the damage to the religious population as resultof the clock change, from the following aspects:
The Morning Prayer – moving the clock moves sunrise one hourforward and also postpones the Morning Prayer by one hour. This makes itdifficult for those who pray to get to work on time.
Problems with fulfilling the Mitzvah of fasting on the Ninth dayof Av and Yom Kippur – it is usually easier to fast in the evening in the hoursbefore bedtime and more difficult to fast in the morning. Because of DaylightSaving Time people go to bed early and get up early, which makes the fast moredifficult.
In 1992 “Daylight Saving Time Law” was enacted, establishingthat Daylight Saving Time will be enforced every year for a period of at least 5months. However, exact dates were not established. The decision about the exactdates was given to the Minister of the Interior, subject to approval of theInternal Affairs and Environment Committee. The need for uniformity over theyears brought on an amendment to the law in 2005, which determined thefollowing:
The move to Daylight Saving Time will always occur on the lastFriday before April 2nd, at 2:00 a.m.
The move back to standard time will occur on the Sunday beforethe tenth day of the Jewish month of Tishrei, at 2:00 a.m. The determination ofthe move back to standard time according to the Jewish calendar ensures that itwill always occur on Saturday night between Rosh Hashanah (the Jewish New Year)and Yom Kippur.
