Black's Law Dictionary
Certain established festivals or holidays in the ecclesiastical calendar. These days were anciently used as the dates of legal instruments, and in England the quarter-days, for paying rent, are four feast-days. The terms of the courts, in England, before 1875, were fixed to begin on certain days determined with reference to the occurrence of four of the chief feasts.
