Tickets for SatanCon 2023, ‘The Largest Satanic Gathering in History,’ Sell Out https://churchleaders.com/news/445920-tickets-for-satancon-2023-the-largest-satanic-gathering-in-history-sell-out.html

"SatanCon 2023, a convention organized by The Satanic Temple (TST) and billed as “the largest satanic gathering in history,” has sold out of tickets. The convention is set to be held in Boston on April 28-30 ... TST has long been politically active, speaking against state abortion bans, and subverting public shows of Christian religion through parody and symbolic battles for representation of their iconography in public spaces. The Satanic Temple has also launched “After School Satan Clubs” at various public schools around the nation as an alternative to on campus Bible studies, providing self-guided activities such as science and craft projects, puzzles, and games, while offering lessons in benevolence, empathy, critical thinking, and creativity."

Prayer and fasting on those 3 days (last weekend of April) seems very appropriate.
