The normal gestation period of a pregnant mare is about 340 days, give or take ten days. If the mare is due to foal in warm weather, she will likely foal on the early side. If she is due to foal in cold weather, she will likely carry a little longer. Since the mare's age and the number of foals she's carrying also influence her due date, a mare may foal early or late regardless of the time of year. It pays to start keeping an eye on your mare at least 10 days before she is due to foal.
The easiest way to calculate the due date is to subtract 25 days from the breeding date. If, for example, the mare is bred in February 27, she will be due to foal approximately on February 2 of the following year.

Horse Pregnancy lasts for approximately 335-340 days. and usually results in one foal (male: colt, female: filly). Twins are rare. Colts are usually carried 2-7 days longer than fillies. Females 4 years and over are called mares and males are stallions

Eleven months and it for some reason seems to take a few days longer for a colt than a filly from my experience anyhow.

11 months, give or take a couple weeks.
Aren't we glad as humans that we don't have to carry that long.
