How the Calculation Works

The calculator uses the average pregnancy duration to estimate the due date. Here's how it works:

The average pregnancy lasts 280 days (40 weeks).
We add 280 days to the conception date to estimate the due date.
The time of day selection helps account for when conception occurred during the day.

This method provides a reasonable estimate but should not be considered exact. Individual pregnancies may vary.

Example Calculation

Let's look at an example to understand how the calculation works:

Example Scenario

If a baby was conceived on January 15, 2023, in the afternoon:

Conception Date: January 15, 2023
Time of Day: Afternoon

The estimated due date would be:

October 12, 2023

This is calculated by adding 280 days to January 15, 2023.

This example shows how the calculator works in practice. The actual due date may vary by several days.
