Enter the start date and select the species to calculate the due date of gestation.

Gestation Calculation Formula

The following formula is used to calculate the due date from the start date and the gestation period. 

Due Date = Start Date + Gestation Period (days)

Variables:

  • Due Date is the estimated date of birth (YYYY-MM-DD)
  • Start Date is the date of conception or start of gestation (YYYY-MM-DD)
  • Gestation Period is the number of days the species is expected to be pregnant (days)

To calculate the due date, add the gestation period to the start date.

What is Gestation Calculation?

Gestation calculation refers to the process of determining the expected due date of an animal’s pregnancy. This involves understanding the specific gestation period for the species, which varies greatly among different animals. Proper gestation calculation ensures better planning and preparation for the arrival of the newborn.

How to Calculate Due Date?

The following steps outline how to calculate the due date using the given formula.

  1. First, determine the start date of gestation.
  2. Next, determine the specific gestation period for the species.
  3. Use the formula from above: Due Date = Start Date + Gestation Period (days).
  4. Finally, calculate the due date by plugging in the values.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem:
