Equine 340 Day Gestation Table
This gestation table is based on a 340 day foaling period. Keep in
mind, some mares may foal earlier and some later, so this table should
only be used as a guide. To use the table, find the month your
mare was bred and the specific date she was bred under the "Breed Date"
column. The mare's suspected foal date is located directly across
from the breed date in the "Foal Date" column.
