Example Calculation

If conception occurred on April 15, 2023:

Due Date = April 15, 2023 + 40 weeks Due Date = April 15, 2023 + 280 days Due Date = February 12, 2024

This means if you conceived on April 15, 2023, your estimated due date would be February 12, 2024.

The pregnancy would be:

Full term (40 weeks) by February 12, 2024
39 weeks by January 14, 2024
