Mare Due Date Calculator
Note: Average gestation period is 340 days (11 months), but can range from 320-370 days.
The Mare Due Date Calculator is a practical tool designed for horse breeders and equine enthusiasts to estimate the expected foaling (birth) date of a mare. By inputting the breeding date and the mare’s gestation period, the calculator provides an accurate due date, along with an early and late range based on natural variation.
Why Is Calculating the Due Date Important?
Knowing the expected foaling date helps horse owners:
- Prepare the mare’s environment for a safe and comfortable birth.
- Schedule veterinary check-ups and monitor the mare’s health.
- Manage breeding schedules efficiently.
- Plan for foal care immediately after birth.
How Does the Mare Due Date Calculator Work?
- Breeding Date: The day the mare was bred.
- Gestation Period: The length of pregnancy in days. The average gestation period for mares is approximately 340 days but can vary between 320 and 370 days.
The calculator adds the gestation period to the breeding date to give the expected due date. It also shows the earliest and latest possible foaling dates based on typical variation.
How to Use the Mare Due Date Calculator
- Enter the Breeding Date: Select the date when your mare was bred.
- Input Gestation Period: The default is 340 days; adjust if you expect a shorter or longer period (range: 320–370 days).
- Click Calculate: Instantly get:
- The expected due date.
- Number of days remaining until foaling.
- Early and late date range for possible foaling.
- Reset: Clear inputs for a new calculation.
Example Scenario
If your mare was bred on March 1, 2026, with an average gestation period of 340 days:
- Expected due date will be around January 5, 2027.
- Early foaling may happen as soon as February 26, 2027 (320 days).
- Late foaling could occur up to February 27, 2027 (370 days).
- Days until due date will be calculated from today’s date.

- Precision: Accounts for natural gestation variability.
- Convenience: Quick and easy-to-use interface.
- Planning: Helps manage mare care and foal preparations.
- Free Tool: Accessible anytime, anywhere.
- Clear Results: Displays all key dates and days remaining.
FAQs About the Mare Due Date Calculator
1. What is the average gestation period for a mare?
The average gestation period is about 340 days (approximately 11 months).
2. Why does the gestation period vary?
Gestation can vary due to mare health, breed, age, and environmental factors.
3. Can I input a gestation period shorter or longer than 340 days?
Yes, you can input between 320 and 370 days to reflect early or late foaling.
4. How accurate is the due date prediction?
It’s an estimate; actual foaling may occur within the early and late date ranges.
5. What if my mare foals before the early date?
Early foaling is possible but less common; monitor the mare closely.
6. Should I rely solely on this calculator for foaling preparation?
No, use it alongside veterinary advice and regular mare monitoring.
7. How can I prepare for foaling?
Ensure a clean, safe environment and have a vet checkup close to the due date.
8. Can the calculator be used for other animals?
No, it’s designed specifically for horse gestation.
9. What if I don’t know the exact breeding date?
Use the best estimate available; accurate input improves predictions.
10. Does the calculator account for multiple breedings?
No, it uses a single breeding date to calculate the due date.
Conclusion
The Mare Due Date Calculator is a valuable tool for horse breeders to estimate foaling dates with ease and accuracy. By inputting the breeding date and gestation period, you can better prepare for your mare’s delivery and ensure the health and safety of both mare and foal.
