please can advise on this, i've tried various methods don't seem able work.

i need countdown from

datetime.now() 

to

datetime(2011,05,05)

you can use

delta = datetime.datetime(2011, 05, 05) - datetime.datetime.now() 

to datetime.timedelta object describing remaining time. number of remaining days delta.days, remaining hours delta.seconds/3600. or delta.seconds//3600.
