This donkey gestation calculator is tool designed to help donkey breeders and owners estimate the due date of a pregnant jenny (female donkey).
This calculator takes into account the average gestation period of donkeys and uses the date of successful breeding or conception to predict when the foal is likely to be born.
Donkey Gestation Calculator
Typical gestation period for donkeys is approximately 365 days (11-14 months).
| Breeding Date | Estimated Due Date | Possible Due Date Range |

Some observations from these calculations:
- Year-long gestation: Notice how the due dates are always in the following year, demonstrating the lengthy gestation period of donkeys.
- Seasonal considerations: Breeding dates in different seasons result in foaling dates in those same seasons the following year. This can be important for planning purposes, especially in regions with extreme weather conditions.
- Holiday considerations: Some breeding dates (like December 25, 2025) result in due dates around major holidays (December 30, 2026). This might affect availability of veterinary care or the owner’s schedule.
- Leap year impact: The calculations account for leap years. For example, the breeding date of January 1, 2024 (a leap year) results in a due date of January 5, 2025, which is 370 days later.
Donkey gestation Calculation Formula
The formula used in a donkey gestation calculator is relatively straightforward:
Due Date = Breeding Date + Average Gestation Period
To use this formula effectively, it’s crucial to know:
- The exact date of breeding or conception
- The average gestation period for donkeys
While the average gestation period is generally consistent among donkeys, it’s important to note that individual variations can occur. Most calculators use an average of 365 to 370 days for donkey gestation.

How long are donkeys pregnant?
The gestation period for a donkey typically ranges from 365 to 376 days, with an average of about 370 days. This is equivalent to approximately 12 to 14 months or 52 to 54 weeks.
To break it down further:
- Minimum gestation: Around 365 days (1 year)
- Average gestation: 370 days (1 year and 5 days)
- Maximum gestation: Up to 376 days (1 year and 11 days)
It’s worth noting that while these figures represent the typical range, some donkeys may fall slightly outside this range. Pregnancies lasting up to 390 days (about 13 months) have been recorded in some cases.
