for some additional help ... marking days of the week (M T W T F S S) along the top.. at least in relief might be a functional addition.
optionally a month name slider could be added at the top - obviously it won't look as "cool"
finally a smaller slider tab might be added to the frame, in order to hide the numbers 29/30/31 as needed. that tab could either be blank or have digits 1/2/3 printed on it (for next month)
