Michaelmas is celebrated in the Waldorf schools, which celebrate it as the “festival of strong will” during the autumnal equinox.

The key element of the Michaelmas festival is that it celebrates inner strength and courage. 

Because Michaelmas falls near the equinox, it is commonly associated with the beginning of autumn. So Waldorf schools also use Michaelmas to teach students the importance of using courage to prepare for the colder, darker, winter months.
It’s symbolic of darkness, so it’s important for children to have warmth inside with them. In addition to honoring St. Michael and marking the beginning of Autumn, Michaelmas represents harvest time – a time when people make preparations for the winter.
