is yom kippur fall equinox
Yom Kippur and the Autumn Equinox: A Comparison. This year, 2007, Yom Kippur falls on Sept. 21 and 22. The equinox falls early on the morning of the 23rd. This year, the autumn equinox falls just after Yom Kippur (5:51 am EDT, Sept. 23). Usually one thinks of Rosh haShanah, the Jewish new year, as the autumn holiday, or of Sukkot, the harvest festival. However, this year we get an unusual chance to focus on Yom Kippur as an autumn equinox holiday.
