calendar moving

hello for a project i'm doing i need somethinh that show quicly the days that pass.It is along a range of 9 months and sometimes is forward oher backward.My idea is to put between scenes some kind of indicator that qucly show the days passed from this event and the next.

In other word  somehing like a calendar  that  move by showing the paper of the day changing quicly

Do you know how can i do that or if i might find some animation to use for the pourpose?

thanks a lot
