Yes, they really have only one time zone. # From Bob Devine (January 28, 1988): # No they don't. See TIME mag, February 17, 1986 p.52. Even though # China is across 4 physical time zones, before Feb 1, 1986 only the # Peking (Bejing) time zone was recognized. Since that date, China # has two of 'em -- Peking's and Urumqi (named after the capital of # the Xinjiang Uighur Autonomous Region).

S. Naval Observatory (January 19, 1989): # ISRAEL 2 H AHEAD OF UTC # ISRAEL 3 H AHEAD OF UTC APR 10 - SEP 3 # From Ephraim Silverberg (April 18, 1989): # Prior to 1989, the rules concerning Daylight Savings Time changed every # year; as information, regarding exact times and dates during this period, # is not readily available at the present time, the rules commence starting # with the year 1989. # From 1989 onwards the rules are as follows: # # 1. Daylight Savings Time commences midnight of the first Saturday night # following the seven-day festival of Pesach (Passover). The transition # is from midnight Israel Standard Time to 1 a.m. Israel Daylight Savings # time. As the Pesach festival is dependent on the Lunar calendar (the # first day is always on the 15th day of the month of Nisan), the rule # changes every year on the Gregorian calendar. # # 2. Standard Time is reinstated on the Saturday night whereupon Jews # following the Ashkenazi (European) rite begin to recite the Selichot # (forgiveness) prayers prior to the Jewish Lunar New Year. The transition # is from midnight Israel Daylight Savings time to 11 p.m. Israel Standard # Time. The law (according to the Ashkenazi custom) concerning the # commencement of the Selichot prayers is described in chapter 128, section # 5 of the "Code of Jewish Law," by Rabbi Shlomo Ganzfried (translated by # Hyman E. Goldin): # # Beginning with the Sunday [**] before Rosh Hashanah [***], # we rise early for the service of Selichot (supplications for # forgiveness). If Rosh Hashanah occurs on Monday or Tuesday, we # begin saying the Selichot from the Sunday of the preceding week. # # This, too, varies from year to year on the Gregorian calendar and, thus, # two explicit timezone rules are required for each Gregorian year. # # [**] actually Saturday night as the Jewish day commences at nightfall. # [***] the Jewish Lunar New Year. # Rule NAME FROM TO TYPE IN ON AT SAVE LETTER/S Rule Zion 1989 only - Apr 30 0:00 1:00 D Rule Zion 1989 only - Sep 24 0:00 0:00 S Rule Zion 1990 only - Apr 22 0:00 1:00 D Rule Zion 1990 only - Sep 16 0:00 0:00 S Rule Zion 1991 only - Apr 7 0:00 1:00 D Rule Zion 1991 only - Sep 1 0:00 0:00 S Rule Zion 1992 only - Apr 26 0:00 1:00 D Rule Zion 1992 only - Sep 20 0:00 0:00 S Rule Zion 1993 only - Apr 18 0:00 1:00 D Rule Zion 1993 only - Sep 12 0:00 0:00 S Rule Zion 1994 only - Apr 3 0:00 1:00 D Rule Zion 1994 only - Aug 28 0:00 0:00 S Rule Zion 1995 only - Apr 23 0:00 1:00 D Rule Zion 1995 only - Sep 17 0:00 0:00 S Rule Zion 1996 only - Apr 14 0:00 1:00 D Rule Zion 1996 only - Sep 8 0:00 0:00 S Rule Zion 1997 only - May 4 0:00 1:00 D Rule Zion 1997 only - Sep 28 0:00 0:00 S Rule Zion 1998 only - Apr 19 0:00 1:00 D Rule Zion 1998 only - Sep 13 0:00 0:00 S Rule Zion 1999 only - Apr 11 0:00 1:00 D Rule Zion 1999 only - Sep 5 0:00 0:00 S Rule Zion 2000 only - Apr 30 0:00 1:00 D Rule Zion 2000 only - Sep 24 0:00 0:00 S Rule Zion 2001 only - Apr 15 0:00 1:00 D Rule Zion 2001 only - Sep 9 0:00 0:00 S Rule Zion 2002 only - Apr 7 0:00 1:00 D Rule Zion 2002 only - Sep 1 0:00 0:00 S Rule Zion 2003 only - Apr 27 0:00 1:00 D Rule Zion 2003 only - Sep 21 0:00 0:00 S Rule Zion 2004 only - Apr 18 0:00 1:00 D Rule Zion 2004 only - Sep 12 0:00 0:00 S Rule Zion 2005 only - May 1 0:00 1:00 D Rule Zion 2005 only - Sep 25 0:00 0:00 S Rule Zion 2006 only - Apr 23 0:00 1:00 D Rule Zion 2006 only - Sep 17 0:00 0:00 S Rule Zion 2007 only - Apr 15 0:00 1:00 D Rule Zion 2007 only - Sep 9 0:00 0:00 S Rule Zion 2008 only - Apr 27 0:00 1:00 D Rule Zion 2008 only - Sep 21 0:00 0:00 S Rule Zion 2009 only - Apr 19 0:00 1:00 D Rule Zion 2009 only - Sep 13 0:00 0:00 S # Zone NAME GMTOFF RULES/SAVE FORMAT [UNTIL] Zone Israel 2:00 Zion I%sT # The following is a chart of the day of the week and Gregorian date of # the first day of Pesach and the first day of Rosh Hashanah for the years # 1989 through 2009 inclusive. # # First Day of Passover # --------------------- # Gregorian Year Day of Week Month Day # -------------- ----------- ----- --- # 1989 Thursday April 20 # 1990 Tuesday April 10 # 1991 Saturday March 30 # 1992 Saturday April 18 # 1993 Tuesday April 6 # 1994 Sunday March 27 # 1995 Saturday April 15 # 1996 Thursday April 4 # 1997 Tuesday April 22 # 1998 Saturday April 11 # 1999 Thursday April 1 # 2000 Thursday April 20 # 2001 Sunday April 8 # 2002 Thursday March 28 # 2003 Thursday April 17 # 2004 Tuesday April 6 # 2005 Sunday April 24 # 2006 Thursday April 13 # 2007 Tuesday April 3 # 2008 Sunday April 20 # 2009 Thursday April 9 # # First Day of Rosh Hashanah # -------------------------- # Gregorian Year Day of Week Month Day # -------------- ----------- ----- --- # 1989 Saturday September 30 # 1990 Thursday September 20 # 1991 Monday September 9 # 1992 Monday September 28 # 1993 Thursday September 16 # 1994 Tuesday September 6 # 1995 Monday September 25 # 1996 Saturday September 14 # 1997 Thursday October 2 # 1998 Monday September 21 # 1999 Saturday September 11 # 2000 Saturday September 30 # 2001 Tuesday September 18 # 2002 Saturday September 7 # 2003 Saturday September 27 # 2004 Thursday September 16 # 2005 Tuesday October 4 # 2006 Saturday September 23 # 2007 Thursday September 13 # 2008 Tuesday September 30 # 2009 Saturday September 19 ############################################################################### # Japan # From Guy Harris # Zone NAME GMTOFF RULES/SAVE FORMAT [UNTIL] Zone Japan 9:00 - JST ############################################################################### # Republic of Korea # From Guy Harris: # According to someone at the Korean Times in San Francisco, # Daylight Savings Time was not observed until 1987.
