Planning estimates
GestationChart provides estimates based on published averages and the calculation methods described on the site. Gestation varies by animal. The tools do not confirm pregnancy and are not veterinary advice. Always confirm pregnancy and discuss individual due dates or health concerns with your veterinarian.
No warranty
The site is provided as available, without a guarantee of accuracy, uninterrupted availability, fitness for a particular purpose, or preservation of local records. Check entries and results before relying on them for farm planning. To the extent permitted by applicable law, we are not responsible for losses arising from use of the site. Nothing here excludes rights or responsibilities that cannot lawfully be excluded.
Your records
You are responsible for the information entered and shared. Keep independent copies of breeding and animal records. Local browser storage may be cleared or unavailable, and a share link is readable by anyone who receives it. The planner is a convenience, not a complete farm record system.
Acceptable use
Use the site lawfully. Do not interfere with its operation, attempt unauthorized access, or use it to distribute malicious content. Share records only when you have authority to do so.
