A Future Pregnancy Calculator is an online tool that helps expecting parents estimate the due date of their baby and track the gestational age. By providing your last menstrual period (LMP) and average menstrual cycle length, the calculator predicts:

  • Your estimated delivery date
  • The current gestational age in weeks and days

This helps parents-to-be prepare for the arrival of their baby, schedule prenatal checkups, and monitor pregnancy progress effectively.

    This is the starting point for calculating gestational age. Accurate input ensures precise results.

  4. View Results:
    The results section displays:
    • Estimated Due Date: The expected date of delivery.

Example Calculation

Let’s go through an example to understand how this tool works:

  • First day of last menstrual period (LMP): March 1, 2025
  • Average cycle length: 30 days

Steps:

  1. Enter March 1, 2025 in the LMP field.
  2. Enter 30 as your cycle length.
  3. Click Calculate.

Results:

  • Estimated Due Date: December 7, 2025
