Hijri ANCPregnancy due date
Clinician-built from the first date
Hijri ANC was created to make pregnancy dating and antenatal planning immediately understandable in both Gregorian and Umm al‑Qura Hijri calendars—without moving clinical data away from the device.

Why Hijri ANC exists
Pregnancy care is time-sensitive, but the calendar used in the clinic may not be the calendar used by the patient. Hijri ANC keeps both dates visible throughout dating results, expected delivery dates, and antenatal milestones.
The application combines standard obstetric calculations with the Umm al‑Qura calendar model in a focused, private workflow designed for everyday clinical use.
