The problem with the Pagan Wheel of the Year is that we are starting with a name, then working out what the day should mean from its etymology and history, and then trying to associate it with the season—which is completely backwards! We need to look at the season, work out what the holy day should mean, and then come up with an appropriate name. The year should turn the Wheel, not the other way around.
While the origins of some forms of contemporary Paganism, like Wicca and Druidry, go back further, the beginning of what is called the “Pagan movement” can be dated to 1967 — making this year the 50th anniversary of contemporary Paganism.
