I am indebted to my ex-colleague at BBN, many decades ago, Larry Denenberg for this information. I would not have worked this out IF not for a detailed e-mail about this by Larry this morning. Larry is also the one, who twice a year, informs me as to when it will be the earliest/latest sunsets in New England — which are NOT necessarily on the same day as the solstice.

Well the Autumnal Equinox for 2015 is at 4:22 EDT on Wednesday, September 23, 2015. Yom Kippur, a.k.a ‘Day of Atonement’, the holiest day of the year in Judaism in 2015 begins in the evening of Tuesday, September 22 and end in the evening of Wednesday, September 23. Thus, definitely for the U.S. East Coast the Autumnal Equinox will occur during Yom Kippur.

The time for each and every equinox is FIXED and invariable across the globe. So Autumnal Equinox for 2015, across the World, happens at 08:22 Greenwich Mean Time (GMT). That is physics and astronomy and there are no local variants. Not so with Yom Kippur. The timing is based per LOCAL sunset. So Yom Kippur in Alton, New Hampshire starts well ahead of Santa Barbara in California.

Larry doesn’t tell me, explicitly, as to when we last had this, though it appears that there was a good chance that it might have happened in some places on 1947 and possibly 1939. Yom Kippur, per the Gregorian calendar, can fall between September 14 (as happened in 1899 and 2013) and October 14 (as happened in 1967 and will happen again in 2043). So that is quite the spread. Larry, however, does point out that in 2034 the Autumnal Equinox will start at 6:38 PM U.S. Eastern time and as such could coincide with Yom Kippur that starts that evening.

You can try and check Larry’s Website for more information. Larry, like all the others that worked at BBN during my short tenure, is quite the intellectual.
