The Foaling Calculator is much easier to use than the Horse Gestation Chart. The gestation chart is when you had to count the days til the due date. This calculator is no way to take away from the need for you to seek a vet’s professional advice. Their opinion is valuable about your mare’s gestation period. There are many items a professional vet will notice about proper care for your horse. Horses need to sleep lying down to meet their REM sleep needs. But they can also sleep standing, but just won’t meet their REM sleep needs.
