Gestation Calculator

This gestation calculator can help you estimate a due date based on date of service and a typical gestation length. Cattle usually have a gestation period between 279 and 292 days. This calculator uses a standardized 283-day gestation period.

Simply plug in the month and day of insemination to get an expected due date.
Or, vice versa: input a desired due date, and the calculator will provide a suggested breeding date.
