Clinical Precision & Methodology
The Pregnancy Due Date Calculator utilizes a cycle-adjusted Naegele's rule to accurately estimate the delivery date (EDD), gestational age, and conception date.
Adjusted Naegele's Rule
Standard calculations assume a strict 28-day cycle. This tool dynamically adjusts the estimated date of delivery based on the patient's exact cycle length for precise dating.
Gestational Age Tracking
Instantly calculates current gestational age in weeks and days, and categorizes the pregnancy into its current trimester.
Thermal Receipt Export
Generates a high-resolution, perfectly scaled PNG image designed specifically for 80mm thermal printers, enabling instant clinical handouts.
