Use our foal calculator to accurately estimate your mare’s expected delivery date based on her breeding date.
How to Use the Foal Calculator
To use this calculator, start by entering the last heat date of the mare in the provided field. Next, enter the average gestation period for a horse, which is typically around 340 days, but this may vary depending on breed and other factors. After you’ve entered both pieces of information, click the “Calculate” button to find out the expected foaling date.
How It Calculates the Results
The calculator takes the last mare heat date and adds the gestation period (in days) to determine the expected foaling date. The result is then formatted to the standard date format (YYYY-MM-DD) to be easily understood.
Limitations of the Calculator
The foal calculator provides an estimated foaling date based on averages. It is essential to note that gestation periods can vary by a number of days for each individual horse. This calculator does not take into account variables specific to each mare, such as age, health, or previous gestation periods, which could affect the actual foaling date. Always consult with a veterinarian for more accurate predictions and mare care.
