Hello everyone. Can someone please explain to me how to account for 13 lunar phases instead of 12 in a year.

Its been described to me that there's been a shift in lunar cycles and its now more spiralic than cyclic.

Divide

365 sun calendar days by 29.5 days in a lunar month = 12.4 or so lunar phases.

Each -- the sun and the moon -- have separate and unrelated cycles. The moon has a 19-year cycle where the moon's phases occur on the same calendar dates.

They do intersect now and then in a fashion.
If you want a visual, I look at it like a biorhythm chart with the way the 3 different cycles intersect on occasion.

Thanks a lot

That helped a great deal. Now I can advance in my studies of our beloved moon with a firm foundation. That information is much appreciated!
