Once Upon a Time ... They Set Aside Some Time for When There Was No Time

Once upon a time, December was the 10th month, and the Roman calendar from January through December covered about 300 days. That left roughly 60 days off the calendar—a stretch of time with no farming schedules, no religious obligations, and not even named months to worry about.
Imagine it: two whole months without tracking months, let alone days. 

Not just free time, but free of time.

Am I the only one who finds that idea incredibly appealing?
