Please enter a valid due date.
Enter a due date and this tool maps the nine dates partners actually ask about: the start, dating scan, end of the first trimester, halfway, anatomy scan window, third trimester, early term, full term, and the due date.
Pregnancy is 280 days from the last period. Each milestone is anchored to a medical week: the calendar date is the pregnancy start plus (week − 1) × 7 days. The due date milestone is the due date itself.
A trip, a wedding, or a work deadline is easier to place when you can see whether it lands before the anatomy scan or after full term. You get the dates once, instead of counting weeks on your fingers every time.
