About GestationPeriod

GestationPeriod gives one clear answer for seven species: the expected due date, the normal window around it, and the next milestone to plan for. Gestation lengths come from breed association charts and university extension guides, and each page lists the figure it uses.

Who runs GestationPeriod

GestationPeriod is written and maintained by Hassan Nawaz (Publisher).

How the numbers are checked

Gestation lengths come from breed association charts and university extension guides. Each page lists the average used and the normal range around it. Every tool runs in your browser, and each page shows its formula so you can check the math yourself. Before publishing, every calculator is tested against worked examples. When a source changes or a reader reports a problem, the page is checked again.

Limits

Dates and timelines are guides for planning. They do not diagnose anything or replace a vet's exam, and the health pages here are general information, not veterinary advice.
