Rabbit Gestation Calculator
This rabbit gestation calculator finds your doe's expected kindling date instantly. Enter her breeding date below to calculate the rabbit gestation period, track week-by-week milestones, and prepare your nesting box.
Quick Answer
The gestation period for a rabbit averages 31 days (approximately 1 month), with a normal range of 28–35 days. Most domestic rabbits kindle precisely on day 31. Enter the mating date above to calculate the exact expected kindling date and key milestones.

How to Use This Calculator
Enter the date your doe was bred using the date picker. Select the breed if known for a slightly more precise estimate. Click Calculate Due Date to see the expected kindling date, earliest and latest dates within the normal range, and a full milestone timeline from implantation to kindling.
The calculator saves your last result in the browser — useful when managing multiple does during a busy breeding season.
Rabbit Gestation Period — What to Expect
The rabbit gestation period averages 31 days, with a normal range of 28–34 days. The gestation period for rabbits is one of the shortest among common domestic animals, reflecting the rabbit's evolutionary strategy of rapid reproduction. The rabbits gestation period is the same whether you're raising commercial meat breeds or pet breeds — all domestic rabbits share the same 28–34 day window.
Days 1–7: After mating, ovulation is triggered within 10–12 hours (rabbits are induced ovulators). Fertilized eggs implant in the uterine horns around day 7. During this critical window, stress, inadequate nutrition, or extreme temperatures can cause early embryo loss.
Days 14–21: The fetuses become palpable through the doe's abdominal wall — an experienced handler can gently feel marble-sized bumps in each uterine horn. This is the time to confirm pregnancy and prepare the nest box.
Days 25–31: The doe begins nesting behavior, pulling fur from her dewlap and chest to line the nest box. Place the nest box in the hutch on day 27–28. Rapid fetal growth occurs during the final week — the doe's food and water intake increases significantly.
Kindling usually occurs in the early morning hours and is typically complete within 30 minutes. Does rarely need assistance during birth. Check the nest box the morning after the expected kindling date to confirm all kits are alive and nursing.

How We Calculate Rabbit Gestation
The rabbit gestation calculator uses the formula: Kindling Date = Breeding Date + 31 days. The 31-day average is based on data from the American Rabbit Breeders Association and validated by university extension research on rabbit production. The range of 28–34 days reflects normal variation across breeds and individuals.
