1. What is NZ Ovul EDD Calculator?

The NZ Ovul EDD Calculator estimates the due date based on the known ovulation date using the standard formula of ovulation date plus 266 days. This method provides an accurate estimated due date for pregnancy planning and monitoring.

2. How Does the Calculator Work?

The calculator uses the NZ Ovul EDD formula:

Where:

• \( EDD \) — Estimated Due Date
• \( Ovulation Date \) — The known date of ovulation
• \( 266 days \) — Standard gestation period from ovulation

Explanation: This calculation method is based on the typical 266-day gestation period from ovulation to delivery, which corresponds to approximately 38 weeks of pregnancy.

3. Importance of EDD Calculation

Details: Accurate due date estimation is crucial for proper prenatal care, monitoring fetal development, planning for delivery, and ensuring optimal timing for medical interventions and preparations.

4. Using the Calculator

Tips: Enter the known ovulation date in the date field. The calculator will automatically compute the estimated due date by adding 266 days to the ovulation date.
