We also have a handy Horse Gestation Calculator here.
Please note, this is just an estimate (even, “guesstimate”) of your mare’s due date. Don’t rely on it, as a mare may foal early or late regardless of the time of year. Keep an eye on the mare at least 10 days before she’s due to foal and talk to your vet or equine expert, as your mare’s circumstances (like her age and the number of foals she’s carrying) may be different, or there may be medical complications.
