Mare Gestation Calculator

Are you wondering when your pregnant mare will foal? Use our Mare Gestation Calculator to find out! The average gestation length in the mare ranges from 320 to 362 days; most mares will foal within 330-345 days of successful breeding. However, mares have successfully foaled with gestation lengths outside this range.

Please Note: The Mare Gestation Calculator is intended for use only as a foaling date estimation tool for horses. It does not consider differences between individual mares.
