The Harvest Moon on the 26th: the Full Moon That Refuses to Rise Later
The full Moon of 26 September rises at 19:19 in Paris, twenty-one minutes before sunset, then only 15 or 16 minutes later on each following evening. In March the same delay reaches 84 minutes. This small geometric miracle has a name, the Harvest Moon, and an explanation that comes down to the angle of the ecliptic against the horizon. The numbers, evening by evening.
