how long is a lunation cycle
The Lunation Number or Lunation Cycle is a number given to each lunation beginning from a certain one in history. Several conventions are in use.or all new moons between 1601 and 2401, the maximum difference is 0.592 days = 14h13m in either direction. The duration of a lunation (i.e. the time from new moon to the next new moon) varies in this period between 29.272 and 29.833 days, i.e. −0.259d = 6h12m shorter, or +0.302d = 7h15m longer than average.
Well, let’s start off with a bit of backstory: For generations, a woman’s monthly cycle has been tied to the moon cycle likely because they’re about the same length–with a “typical” menstrual cycle lasting 28 days and a lunar cycle lasting 29.5 days.n the study, women with abnormally long cycles of about 45 days who slept with a 100-watt bulb turned on at night in their bedroom from Day 13 to Day 17 of their cycle successfully shortened their periods to about 33 days.
