Health Calculator FAQs
How is my due date calculated?
The Due Date calculator estimates your due date from the first day of your last menstrual period using the standard 280-day / 40-week rule.
How does the baby growth percentile work?
It estimates weight-for-age percentile for ages 0-24 months, giving a reference range compared to typical growth curves.
What does the contraction timer do?
It times labor contractions, tracking duration and spacing, and highlights the 5-1-1 pattern (contractions 5 minutes apart, 1 minute long, for 1 hour) that signals it is time to call your provider.
Can I convert oven temperatures for baking?
Yes. The Oven Temperature Converter converts between °F, °C, Kelvin, and UK gas marks for recipes.
