## Origin

Probably a reference to the passing of as many Sundays as there are days in a month, a duration of between twenty-eight and thirty-one weeks. The phrase suggests a temporal extension that is technically quantifiable but socially tiresome. It likely draws its weight from the traditional character of the day, as a month composed entirely of Sundays would offer a considerable stretch of quietude. (disputed)
