Weeks ↔ months converter

Pregnancy months are not four weeks each — nine months of ~4.4 weeks add up to 40 weeks, not 36. This tool uses the same nine-month bands as our monthly guide, so the month it gives you matches the article you'll read next.

This guide is general information, not medical advice. It does not replace a doctor, and it knows nothing about your particular pregnancy. If something feels wrong, contact your doctor instead of waiting for the next scheduled visit.
