Rabbit Gestation Calculator

How to use the rabbit gestation calculator

1. 1. Choose what you know. Enter the breeding date to get a due date, or switch to the target due date mode to work backwards to the breeding date you need.
2. 2. Refine the inputs. The calculator uses the 31-day average for this species.
3. 3. Plan around the range. Use the earliest and latest dates and the milestone timeline to schedule checks, feed changes and preparation of the kindling area.

How long is a rabbit's gestation period?

The average is 31 days from breeding to kindling, about 1 month. Anything between 28 and 33 days is normal, and a typical litter is 4-12 kits. Treat the calculated date as the middle of that window rather than a fixed appointment.

Rabbit gestation table: breeding date to kindling date

Breeding dates one week apart with the matching kindling date at 31 days.

Working backwards from a target kindling date

If you want kits on the ground in a particular week, switch the calculator to target date mode and enter the date you are aiming for. It subtracts 31 days to give the breeding date to book, plus the earliest and latest service dates that still land inside your window.
