[Answered ]-Django date.day queryset lookup

Django doesn’t support filter methods like __lt, __gt, __in on date field attributes. There’s a ticket about this #6439.

You can do the filter you want using extra:

day = 2
Entry.objects.extra(where=["EXTRACT(day FROM from) <= %s"], params=[day])

I’ve tested the above with MySQL, the syntax may be different for other SQL backends.
