Iran uses DST again

Hi all, From 2008, Iran uses DST again which was not used for some years. In Jalali calendar, it starts on 1/1 and it'll end on 06/30. In Gregorian calendar, it starts on 03/21 and ends on 09/21. But every 4 years (2008 is one of them) on our leap years, it'll become 03/20 and 09/20. I was unable to find any English reference, but anyway, the following references mention this change. The latter contains the exact text of the law: http://fa.wikipedia.org/wiki/%D8%AA%D8%BA%DB%8C%DB%8C%D8%B1_%D8%B3%D8%A7%D8%... http://www.rooznamehrasmi.ir/Detail.asp?CurPage=2&NewsID=993144394738441 Thanks, Hedayat
