Look up any breeding date to find the calving date, or print the whole year. The chart uses the standard 283-day gestation; switch to 280 days or a breed average below. For one cow, a bull exposure window or a reverse plan, use the cow gestation calculator.
Cattle, 283-day gestation. Find the date the cow was bred in the left column; the expected calving date is on the right.

How to read the chart
Find the month the cow was bred, then the day. The date beside it is when she is due to calve. Real calving dates scatter around it: in a 2024 study of more than 10,000 AI-bred beef cows, the average was 280 days, and the shortest and longest gestations recorded were 253 and 300 days.
Which length should I use?
283 days is the traditional figure behind most printed charts. Breed matters: in the USDA Meat Animal Research Center comparison, Holstein-sired calves averaged 281 days, Simmental 286, Limousin 288 and Brahman 291. A 1952 study recorded 281.7 days for Angus and 286.1 for Hereford. Pick the preset closest to your herd, or use the calculator to enter an exact number.
Printing
Use the Print button. The menus and ads are hidden on paper, and each month stays together where possible. The chart prints on about three pages.
