Mabon around the world!
Among the Druids:
They celebrate the autumn equinox named Alban Elfed: meaning Water Light. Druids note that darkness lasts longer than light. They honor the equinox as a time to thank The Mother (Concept of the Divine Feminine) for her abundance which manifests in the harvest.
Among the Greeks:
Modern Hellenists celebrate Boedromion which means September in Greek. This festival begins at sunset on the first new moon of September and honors various harvest gods for the next nine days, reminiscent of the festival of Eleusis. Each day, Hellenists make offerings and drink libations to these gods in gratitude for a bountiful harvest.
Among neopagans:
They celebrate Mabon as a day of personal balance, devising their own rituals or honoring the change of seasons in their daily lives.
Among the Celtics:
The autumn equinox is called the festival of Avalon, Avalon being the land of apples, and apple picking often takes place during this time.
Among the Italians / Strégheria:
The autumn equinox is called: Equinozio di Autunnno, honoring the earth/ The lord of light becomes the lord of shadows and the god Janus dies and goes to the underworld.
Primarily and predominantly the Mabon festival is a festival that honors the harvests and crops that the Mother Goddess gives us before the Dark season arrives in earnest.
