Django query datetime for objects older than 5 hours

now = datetime.datetime.now()
earlier = now - datetime.timedelta(hours=5)
MyModel.objects.filter(my_date_field__range=(earlier,now))

That should do the trick.

If Widget is the name of your model, and it has a DateTimeField attribute named created, the query would be:

from datetime import datetime, timedelta

time_threshold = datetime.now() - timedelta(hours=5)
results = Widget.objects.filter(created__lt=time_threshold)

Note that created__lt means "created is less than".
