Saterdee is the day after Fridee and the day before Sundee.
The "ee" ending on the days of the week are a spoken
colloquialism, attributed mostly to the Southern, Southeastern and Western U.S., but may also be found in localized dialects of
Pennsylvania and Maryland and several other states. The roots of this
pronunciation may be traced back to Medieval English. The modern dialectic in the U.K. is often attributed to South East England and London.
