that'd be super cool. one or two days off every month! (in addition to weekends)!

  In the pre-computer days it would make things like computing interest harder. In Rome, interest and rent were mostly computed by the month, and the days inserted to keep the calendar aligned were deliberately between years to make these calculations easy to do (no interest or rent was due, and they could not be used as start or stop days of contractual relationships). Using a pencil influenced other modern things too, like the Dow indexes and GDP.
