As a witch you need a planner like everybody else: to keep track of appointments. But you also need a calendar to keep track of something most people ignore: the phases of the moon, the movement of the sun in the sky, conjunctions, mercury going retrograde… etc.
You need all that to keep up with the Wiccan holidays and ceremonies. Whether it’s Samhain or Beltane, Litha or Mabon – their dates move with the moon, not the sun, so they’re hard to keep track of. Thankfully Llewellyn creates calendars and planners just for you! I’ve gathered the most popular ones on this page.
