Re: Egypt plan to [cancel] DST during Ramadan and then to resume DST again.
We have this at http://www.almasryalyoum.com/en/news/clocks-go-back-during-ramadan-and-then-...: In a statement released yesterday, the cabinet clarified that clocks will move back by one hour at midnight on Tuesday 10 August, to be moved forward again after Ramadan, on Thursday 9 September. Clocks will roll back once more on Thursday 30 September to put the nation on winter time, as stipulated by law. Mosslem Shaltout, professor of solar-space physics and vice-chairman of the Arab Union for Astronomy and Space Sciences (AUASS), said Ramadan will start, atronomically speaking, on Wednesday 11 August. According to Shaltout, the moon's crescent will appear at 6:08 AM on 10 August, when the moon is on the same level with the sun and earth, marking the beginning of Ramadan. Mosslem Shaltout is said to refer to an August 10 crescent moon, and also is said to refer to an August 11 start of Ramadan. We also have this at http://www.timeanddate.com/news/time/egypt-ends-dst-2010.html: DST ends and clocks will move one hour back at midnight (00:00) between Tuesday August 10, and Wednesday August 11, in 2010. Egypt will revert back to DST after Ramadan and move their clocks forward at midnight (00:00) between Thursday, September 9, and Friday September 10, 2010. Egypt will end its 2010 DST schedule at midnight (00:00) local time between Thursday, September 30, and Friday, October 1. Perhaps the clearest translation to rules is: Rule Egypt 2010 only - Aug 11 0:00 0 - Rule Egypt 2010 only - Sep 10 0:00 1:00 S The first rule behaves the same way as what's now in the "africa" file; the second rule restarts DST a day later than what's now in the file. --ado
6:08 am is the time of the new moon, not the time that the crescent will appear. The crescent moon that marks the beginning of the Muslim month can only be seen in the evening. It would be first visible on the evening of August 10 or 11. http://moonsighting.com/vis-maps.html suggests it will be August 11 for the Middle East. This suggests the Ramadan would begin on the evening of August 11. It seems, then that they will make the switch about 18 hours before the beginning of Ramadan, which seems quite reasonable. However, according to wikipedia, Ramadan starts on August 10. Other websites show it starting on August 11. Go figure. The first full day of Ramadan, by the traditional definition, should be August 12. Aaron On Thu, Jul 29, 2010 at 4:54 PM, Arthur David Olson <olsona@elsie.nci.nih.gov> wrote:

By traditional definition, the Islamic month is based on the sighting of the first crescent of the moon, which depends on the observers, not a chronological or mathematical formula, and varies depending on the location of the observer, the weather, the time of day, and other factors. But not not all Islamic countries use the first sighting of the crescent Moon to signal the start of the month. In Saudi Arabia and Egypt the beginning of the month is fixed by the relative timing of sunset and moonset on the 29th day of each month. If the Moon sets before the Sun the next day is the 30th of the month. If the Sun sets before the Moon (by at least 10 minutes in Egypt) the next day is the first of the next month.
