Formula Used

The calculator uses standard pregnancy duration assumptions:

Conception Date = Due Date - 280 days Current Pregnancy Week = (Current Date - Conception Date) / 7

These calculations are based on the average 280-day pregnancy duration. The calculator also accounts for leap years when calculating dates.

Worked Example

Let's calculate for a baby due on June 15, 2024:

Example Calculation

Conception Date: June 15, 2024 - 280 days = September 12, 2023

If today is January 1, 2024:

Days since conception: (January 1, 2024 - September 12, 2023) = 121 days

Pregnancy week: 121 / 7 ≈ Week 17

This example shows how the calculator estimates pregnancy progress based on the due date.

Interpreting Results

The calculator provides several key pieces of information:

Conception Date: Estimated date of fertilization
Current Pregnancy Week: Progress through pregnancy stages
Estimated Delivery Date: Your due date
Milestones: Important developmental stages

Remember that these are estimates. Actual pregnancy duration may vary by several weeks.
