Horse Due Date Calculator

Horse breeders, enthusiasts, and equine veterinarians understand the importance of precise planning during a mare’s pregnancy. Knowing when a mare is likely to foal allows for better care, preparation, and monitoring. The Horse Due Date Calculator is a specialized tool designed to simplify this process by estimating a mare’s foaling date, calculating the gestation period, and providing valuable insights into foaling windows.

This article will guide you step-by-step on how to use the Horse Due Date Calculator, discuss its features and benefits, provide practical examples, and answer the most common questions about equine pregnancy tracking.

What is the Horse Due Date Calculator?

The Horse Due Date Calculator is an intuitive online tool that helps users estimate the foaling date of a mare based on the date of last breeding and the average gestation period. It allows breeders to:

• Calculate the estimated foaling date accurately.
• Track the number of days remaining until foaling.
• Identify the optimal foaling window (320–360 days after breeding).
• Monitor the mare’s pregnancy with actionable insights.

This tool is particularly useful for breeders managing multiple mares, equine veterinarians advising clients, and horse owners who want to stay informed about their mare’s pregnancy.

Step-by-Step Instructions: How to Use the Horse Due Date Calculator

Using the Horse Due Date Calculator is simple, fast, and requires only a few pieces of information. Follow these steps:

Step 1: Enter the Date of Last Breeding

Select the date your mare was last bred or conceived. This is the starting point for all calculations and will be used to determine the estimated foaling date.

Step 2: Select the Gestation Period

Choose the average gestation period for your mare. The tool provides three options:

• 340 days (Average) – suitable for most mares.
• 320 days (Short) – for mares with shorter pregnancies.
• 360 days (Long) – for mares with longer pregnancies.

Step 3: Optional – Enter the Mare’s Name

If desired, you can enter the mare’s name. This feature personalizes the results, making it easier to track multiple horses.

Step 4: Click “Calculate”

Press the Calculate button. A progress bar will appear, showing the calculation in progress.

Step 5: Review Your Results

Once calculations are complete, the tool will display:

• Estimated Foaling Date
• Breeding Date
• Gestation Period
• Days Remaining until foaling
• Foaling Window (range of possible foaling dates)
• Mare’s Name (if provided)
• Dynamic Foaling Note with advice based on how close the mare is to her due date

Step 6: Copy or Share Results

Use the Copy Results or Share Results buttons to save or share your mare’s pregnancy information with your team, veterinarian, or other breeders.

Practical Example

Imagine you bred a mare named “Bella” on January 15, 2025, and you want to calculate her estimated foaling date.

1. Enter January 15, 2025, in the Date of Last Breeding field.
2. Select 340 days (Average) for the gestation period.
3. Enter Bella as the mare’s name.
4. Click Calculate.

The tool calculates:

• Estimated Foaling Date: December 20, 2025
• Days Remaining: 113 days (based on the current date)
• Foaling Window: November 1, 2025 – December 21, 2025

This information allows you to start preparing Bella’s foaling area and monitor her closely as the date approaches.
