Date and Time for Screen saver AS3

I have 5 movieclips:

day1_mc
day2_mc
day3_mc
day4_mc
day5_mc

I’m creating a screen saver where day1_mc will play on the first day the screen saver is initiated , then day2_mc will play at 12:00am on the 2nd day, then day3_mc will play on the start of the next day at 12:00 am and so forth until the 5 day cycle is up, it will loop back to day1_mc.

Any help? Thanks
