حاسبة موعد الولادة

نظرة عامة

A due date estimates when a baby is likely to arrive, typically about 40 weeks from the first day of the last menstrual period. This calculator gives that estimate instantly from your last period date. It is a guide — only a small share of babies arrive exactly on the due date.

كيفية الاستخدام

2. 2

   Adjust cycle length if needed

   The default assumes a 28-day cycle.

3. 3

   Read the estimated due date

   It also shows roughly how many weeks along you are.

كيف يعمل

The most common method (Naegele's rule) adds 280 days (40 weeks) to the first day of your last menstrual period, assuming a regular 28-day cycle. The tool can adjust for cycle length. Because conception timing varies, the result is an estimated date, with normal full-term delivery occurring anywhere from 37 to 42 weeks. A healthcare provider can refine it with an ultrasound.
