How can I find the nearest 15 (or 10) minute interval in python ? e.g.
>>> datetime.datetime.now() datetime.datetime(2011, 2, 22, 15, 43, 18, 424873) I'd like the current 15 minute interval (15:30-15:44) so I'd like to transform the above datetime to a
datetime.datetime(2011, 2, 22, 15, 30, 00, 00) Quite the easiest way to me:
from datetime import datetime, timedelta now = datetime.now() now = now - timedelta(minutes = now.minute % 15, seconds = now.second, microseconds = now.microsecond ) Hope that'll help.
I think for this case using replace is more straightforward than timedelta:
>>> import datetime >>> now = datetime.datetime.now() >>> now.replace(minute=(now.minute - (now.minute % 15)), second=0, microsecond=0) datetime.datetime(2012, 3, 23, 11, 15) >>> 
Just set minutes on
min = min - min % 15 and set shorter time units (seconds, msec, ..) on 0
