What is Mabon?
Mabon is one of the eight critical points on the Wheel of the Year. It marks the official transition from the light half of the year to the dark half of the year. Because it begins on the autumn equinox, the amounts of daytime and nighttime are perfectly balanced. From here on out, the days will grow shorter until Yule.
Mabon is neo-pagan holiday all about the harvest. It is a modern celebration that encompasses many different traditions and events from around Europe and North America. Think of this day as a "pagan Thanksgiving." The name Mabon comes from the Mabinogion, which is a collection of stories and texts from Wales.
I personally treat the Sabbats/Wheel of the Year as seasons. What this means is that it will be Mabon until it is Samhain. I use the official day as a sort of kick-off event or marker. Towards the end of Mabon, bits of Samhain will begin to bleed through. A good way to understand this is like how we begin to see signs of spring before winter has concluded.
