From calculating gestational age via Naegele's rule to dosing pediatric antipyretics safely by weight according to American Academy of Pediatrics (AAP) standards, our suite provides reliable tools built with complete client-side data privacy.
Track gestational age in weeks and days, trimester transitions, and visual fruit size comparisons throughout all 40 weeks of healthy human gestation.
Calculate safe Acetaminophen (Tylenol, 10–15 mg/kg) and Ibuprofen (Advil/Motrin, 10 mg/kg) liquid dosages based on exact body weight rather than variable age bands.

A standard pregnancy due date is calculated by adding 280 days (40 weeks) to the first day of your last menstrual period (Naegele's rule), adjusted for cycle length.
Q:How is pediatric medication dosage calculated by weight?
Pediatric liquid medication doses are calculated based on the child's body weight in kilograms rather than age, following American Academy of Pediatrics (AAP) dosage guidelines.
Q:How accurate is the child height predictor?
The Khamis-Roche mid-parental height formula calculates adult height within a ±2 inch (±5 cm) standard margin of error for 90% of healthy children.
Q:How does IVF due date calculation work?
IVF due dates add 261 days to a 5-day embryo transfer date or 263 days to a 3-day embryo transfer date to determine your exact full-term due date.
Q:Are my family health and pregnancy details kept private?
Yes. All health calculations occur 100% locally in your web browser. No medical dates or personal health figures are ever stored or uploaded to any server.
