Jak vypočítat Due Date Calculator

Co je Due Date Calculator?

A due date calculator uses your last menstrual period (LMP) to predict when your baby will be born. The standard method (Naegele's Rule) adds 280 days (40 weeks) to the LMP. Due dates are estimates — only 4% of babies arrive on the exact predicted date.
