Example

from datetime import timedelta

from django.utils import timezone
from psycopg2.extras import DateTimeTZRange

# To create a "period" object we will use psycopg2's DateTimeTZRange
# which takes the two datetime bounds as arguments
period_start = timezone.now()
period_end = period_start + timedelta(days=1, hours=3)
period = DateTimeTZRange(start, end)

# Say Event.timeslot is a DateTimeRangeField

# Events which cover at least the whole selected period,
Event.objects.filter(timeslot__contains=period)

# Events which start and end within selected period,
Event.objects.filter(timeslot__contained_by=period)

# Events which, at least partially, take place during the selected period.
Event.objects.filter(timeslot__overlap=period)
