Happy Easter and Happy Passover. I do just love religious holidays that have their roots in the movements of planetary bodies! Easter is calculated as the first Sunday after the paschal full moon that occurs on or after the vernal equinox. If the full moon falls on a Sunday, then Easter is the following Sunday. The holiday can occur anywhere between March 22 and April 25. Of course, since Passover came first it too follows an astronomical path. Passover begins on the night of a full moon after the northern vernal equinox.
While you are enjoying your Easter meal remember that the word derives from Eoestre the pagan celebration in honor of the young goddess who would shower d the countryside with eggs during the vernal equinox.
Which ever Spring celebration you partake in have fun and remember they are wonderful connections to the universe and the stars above us.
