African elephant Gestation Calculator
A african elephant's gestation period is about 645 days, or roughly 21 months, though it ranges from 640 to 660 days depending on breed and individual animal.
How to use the african elephant gestation calculator
- 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. Refine the inputs. The calculator uses the 645-day average for this species.
- 3. Plan around the range. Use the earliest and latest dates and the milestone timeline to schedule checks, feed changes and preparation of the calving area.

Working backwards from a target calving date
If you want calfs on the ground in a particular week, switch the calculator to target date mode and enter the date you are aiming for. It subtracts 645 days to give the breeding date to book, plus the earliest and latest service dates that still land inside your window.
