Human Gestation Calculator

Pregnancy is a time of anticipation, excitement, and planning. Knowing your expected due date and tracking gestational age are vital for both expecting parents and healthcare providers. The Human Gestation Calculator is a simple, reliable tool designed to provide accurate estimates of your pregnancy milestones.
