According to the U.S. Naval Observatory, the hours of daylight will not equal the hours of night (that is, 12 and 12) until September 26! What gives? I thought the whole point of having an equinox was for day to equal dark. So what’s so special about today, September 21?
Granted, this is information for Los Angeles, but shouldn’t it be the same all over the world?
Thanks for the info. BTW, I input some more dates for 2002 at the USNO site, and I found the following:
Sunrise and sunset were exactly 12 hours apart on March 16, 5 days before the “traditional” spring equinox. Just as the other 12-12 day, September 26, will be 5 days after the “traditional” fall equinox.
June 21 and December 21 were, indeed, the longest and shortest days of the year. However, June 21 was part of a three-day block of days that all had the same hours of daylight. December 21 will be part of a one-week block of days, all the same.
