A rabbit pregnancy lasts about 31 days from the breeding date, which is 4 weeks and 3 days; most births fall between day 31 and day 33. Day 0 is the breeding date, so week 1 is days 0 to 6, week 2 is days 7 to 13, and so on.

Week by week: days and dates
Dates for a rabbit bred on Mar 1, 2027. Pick your own breeding date in the calculator above.
Day 28: Put the nest box in · Day 31: Due date (kindling) · Day 33: Latest usual date
Week 1 (days 0–6): breeding
Day 0 is the breeding date. If she was bred on several days, the calculator counts from the first breeding and the usual window runs to the last breeding + 33 days.
Put the nest box in on day 28 (28 to 29 days after breeding, MSD Veterinary Manual); does usually kindle on day 31 to 33.
Week 2 (days 7–13)
Nothing on the schedule until day 15 (halfway, week 3). By day 13, 18 days are left to the due date.
Week 3 (days 14–20): halfway
Day 15 (Mar 16, 2027) is halfway through a 31-day pregnancy. From here, 16 days are left to the due date.
Week 4 (days 21–27)
Nothing on the schedule until day 28 (the nest box goes in, week 5). By day 27, 4 days are left to the due date.
Week 5 (days 28–33): the nest box goes in, the due date and the usual window closes
Day 28 (Mar 29, 2027) is the day the nest box goes in, 3 days before the due date.
Day 31 (Apr 1, 2027) is the due date, the average length counted from breeding. It is an estimate; most births fall between day 31 and day 33.
Day 33 (Apr 3, 2027) is the latest usual date. If that day passes, or anything about the mother worries you, call your veterinarian.
