Celtic Moon Calendar

When I was in university I had the chance to work on a book project of my choice (hello, book design 101!) and I created a book called Celtic Sacred Trees. The idea of tying trees into the lunar cycle just made so much sense to me. It meant a closer relationship between the moon we see at night and the trees we see during the day. To have the earth and sky together in one calendar? I was hooked. Plus, I was exploring the Celtic tree calendar for university credits, which was a wonderful added bonus. Like many ancient cultures, the Celts recorded the passing of time by watching the waxing and waning of the moon. The Celtic year was blocked off into 13 divisions to correspond with the 13 annual lunar cycles.  Today, most modern pagans and druids follow a celtic calendar of trees that uses “fixed dates” each month, rather than strictly adhering to the lunar cycle. Our regular Jan-Dec Gregorian calendar is based on a solar cycle, so this fixed date system makes sure that the calendar years don’t fall too far out of synch.

Those who know me well would say that I am a total  a̶s̶t̶r̶o̶n̶o̶m̶y̶ ̶g̶e̶n̶i̶u̶s̶  wannabe astronaut.  My husband and I play with our telescope often, and I absolutely love to be able to pull up this list and check out what full moon we are under, and what the myths and legends associated with the month are. Full moons are one of those simple things in life that I always try to appreciate.
