Rabbit gestation calculator.
Find out when your rabbit is due. Enter the mating date and the calculator estimates the due date from the average rabbit gestation, with the earliest and latest dates too.
Mating date
LiveRabbit gestation lasts about 28 to 35 days, averaging near 31. The due date is the mating date plus the average gestation; the range gives the earliest and latest.

How it works
Counting from mating
Rabbit gestation lasts about 28 to 35 days from mating, about a month, with an average near 31 days. The calculator adds the average to the mating date to estimate the due date, and the 28 to 35 day range gives the earliest and latest you should expect kits.
First-time does and large litters can shift the date by a day or two. Treat the due date as a window of a few days rather than a single fixed day.

How long rabbits carry, the stages to expect, and when to get help.
How long are rabbits pregnant?
Rabbit gestation runs about 28 to 35 days from mating, averaging around 31, or about a month. Counting from the mating date gives the most reliable estimate of when kits are due.
First-time does and large litters can shift the date by a day or two.
Stages of pregnancy
There is little to see early on. The doe’s abdomen enlarges from around two weeks, when the kits can sometimes be gently felt, and in the last days she pulls fur and gathers bedding to build a nest.
Rabbit gestation is short, so signs appear and progress quickly compared with larger animals.
Preparing for the birth
Place a nest box in the hutch around day 28 and keep the doe calm, with constant fresh food and water. Avoid disturbing the nest she builds, and most does kindle overnight without help.
Fur-pulling and nest-building in the final days are clear signs kindling is near.
When to call the vet
Contact a vet if the doe passes about 35 days, since rabbit pregnancy rarely runs longer and a delay can mean trouble, or if she seems unwell after kindling. This tool is for planning only and does not replace veterinary care.
The formula
Date plus
gestation.
The due date is the mating date plus about 31 days, with kits normally arriving between 28 and 35 days.

Rabbit gestation questions.
How long is a rabbit pregnant?
+
About 28 to 35 days from mating, averaging around 31 days, about a month. The calculator uses this to estimate the due date.
How do I calculate a rabbit due date?
+
Add about 31 days to the mating date. Enter that date above and the calculator gives the estimated due date plus the earliest and latest.
Can the due date be a few days off?
+
Yes. First-time does and large litters can shift the date by a day or two. Treat the result as a window from 28 to 35 days.
When should I contact a vet?
+
Contact a vet if the pregnancy runs well past 35 days, if labour stalls without progress, or if the animal seems distressed. A prenatal check-up is always worthwhile.
Is this rabbit gestation calculator free?
+
Yes. It is completely free with no sign-up, and every calculation runs locally in your browser, so nothing you enter is stored or sent anywhere.
