The Gregorian calendar didn’t exist for Iron Age celts so they did not celebrate Beltane on 1 May - but it’s still a wonderful time to celebrate Beltane with most of the rest of the world today 🤩
The Coligny calendar has the date of Bealltainn as the second new moon after the Spring Equinox and this year… that’s the 8th May. My preference!
The astrological date when the sun is around 9 degrees in Taurus: there’s no evidence the celts used this date but they might’ve! (4/5th May this year)
