Formula and assumptions
The calculator uses the formula displayed on the calculator page. Review each assumption, unit and default before interpreting the result.
Worked example
A breeding date of March 1 with a 150-day gestation gives an estimated kidding date about 150 days later, with the selected window shown around it.
How to improve the estimate
Use current, source-specific values. Check product documentation, official rules, measured data or professional guidance when the result affects an important decision.
Important limitations
Actual gestation length varies by breed, litter size, doe health and breeding-date certainty. The calculated date is an estimate rather than a diagnosis.
