END OF SUMMER

In San Diego the day lilies go on blooming long after the autumnal equinox occurs, which this year happens at 3:40 tomorrow afternoon; so technically today has been the last summer day north of the equator. The word "equinox" derives from the Latin words for equal and night (aequus and nox). Tomorrow at the equator night and day will be of approximately equal length, and from then until the winter solstice occurs just past noon (12:02) on December 21, the days will grow shorter. Day lilies and people in San Diego don't notice much of a difference.
