Rabbits normally kindle 28–35 days after mating (about 31 days). Prepare a quiet nest box a few days before the earliest date. Not veterinary advice: this is an estimate for planning only. Always confirm care, feeding and health decisions with a qualified veterinarian.

How to use this tool

1
Enter the breeding date

Use the date of mating or insemination for the rabbit.

2
Read the due window, not just one day

Normal gestation runs 28–35 days, so plan around the whole window.

3
Watch from the start of the window

Prepare housing, feed and a birthing area before the earliest due date.

4
Confirm with a vet

Pregnancy checks, scans and birth planning are a vet’s job, not a calculator’s.

Formula & worked example

Due window = breeding date + 28 to 35 days. Average due date = breeding date + 31 days. First litters and large litters can shift timing within the range.

A breeding date of 1 January 2026 gives an average due date 31 days later, with the normal window spanning 28–35 days after breeding.

Limitations — read this before you rely on it

Gestation varies by breed, age, litter size and individual animal, so births outside the 28–35 day window are possible. This tool estimates dates only and cannot confirm pregnancy or predict litter size. Not veterinary advice: this is an estimate for planning only. Always confirm care, feeding and health decisions with a qualified veterinarian.

Frequently asked questions

Typically 28–35 days, averaging about 31 days.

No — it is the middle of the normal range. Healthy births happen across the whole window.

Contact a veterinarian promptly rather than waiting; overdue pregnancies can need intervention.

No. Only veterinary examination or scanning can confirm pregnancy.
