Really now? In the range of one week before the new moon until one week after, plus one week before the full moon until one week after? How extraordinary.
Jeff: Yes. See ... oh crap, Bill didn't post here. Let me paste from facebook: "4 weeks of 7 days gives 28 days (and the Synodic Month is really 29.5 days, not 28), which leaves a day or two at the end of the month for the remaining 10%." (From my friend Bill Gawne, astronomer.) (and hi, Jeff :D )

ReplyDeleteHi Mary!
ReplyDeleteBy my math, 28/29.5 = (roughly) 94.9%, which is why I was 90% seemed low to me.
