Quarter Days

I find the idea of quarter days fascinating. Quarter Days are medieval dates that correspond roughly to our modern divisions of spring, summer, fall, and winter. They served to mark the quarters of the year for legal purposes. They are below (with the corresponding season):

The Annunciation (Spring, March 25)
The Nativity of St. John the Baptist (Summer, June 24)
Michaelmas / Feast of Michael and All Angels (Fall, September 29)
Christmas (Winter, December 25)

It makes me kind of yearn for the days when a society is so culturally Catholic that we would orient ourselves around the Church Year. We are left to do it ourselves I guess.
