February 15th, Lupercalia:

Celebration of bodily autonomy, sexual liberation, and reproduction

Based on the Roman festival of the same name, Lupercalia falls on February 15. In keeping with the ancient tradition, February 13th and 14th are observed as feast days leading up to the actual holiday. What we are translating this to in TST is a “hail yourself” day. This idea offers a parallel to the “others-centered” traditions of Sol Invictus.

April 30th, Hexennacht:

Occasion honoring those who fell victim to superstition and pseudoscience, whether by witch hunt, Satanic panic, or other injustices

In Johann Wolfgang von Goethe’s Faust: a Tragedy (1808), Mephisto and Faust attend the Walpurgisnacht revelry atop Mount Brocken. Hexennacht a solemn holiday to honor those who were victimized by superstition.

July 25th, Unveiling Day:

A centerpiece of the religious movement and icon of modern Satanism, the Baphomet with Children statue was commissioned by The Satanic Temple in 2014 and created by Mark Porter with “respect for diversity and religious minorities” in mind. On July 25, 2015, The Satanic Temple unveiled Baphomet to a large crowd of devotees in Detroit, signaling the beginning of the new Satanic era. We observe this milestone in Satanic history by celebrating Unveiling Day. (And yes, I am aware that Satanists celebrate other things about this if they are not members of The Satanic Temple so am choosing to leave this one up here on the list.)

October 31st, Halloween:

Halloween is consistently described as evil, demonic, and satanic by those steeped in religious dogma. Costumes, candy, and facing fears are to be embraced.

December 25th, Sol Invictus:

The cult of Sol existed within Rome since its early days as a republic, and Invictus was an epithet used for Jupiter, Mars, and Apollo (among others). The festival celebrated these gods and may have also been used to celebrate the winter solstice.
