Pregnancy Countdown

Enter the first day of your last period and we'll count down to your estimated due date (the standard 40-week rule), live, down to the second.

First day of last period

Only about 5% of babies arrive on their exact due date, this countdown is a statistical estimate, not a guarantee. Your care provider's own dating takes precedence, especially after an early ultrasound.

Watching the seconds tick down is more fun than useful, honestly, but there’s nothing wrong with a little fun during pregnancy. Here’s what the pregnancy countdown is actually built on, and why it’s worth holding loosely.

It’s the Same Math As Your Due Date, Just Ticking

This countdown uses the exact same 40 week estimate as our due date calculator. It doesn’t know anything more about your specific pregnancy than that calculator does. It’s just presenting the same number in a way that’s a bit more fun to watch than a static date on a calendar.

The Clock Will Probably Hit Zero Before Your Baby Arrives

Full term covers a five week window, from 37 to 42 weeks, and plenty of healthy babies show up after their due date, especially first babies. Watching this countdown reach zero without going into labor is common, not a sign anything is off. Treat zero as “somewhere in the neighborhood,” not a hard deadline.

Making the Wait Feel Shorter

A few things tend to help the final stretch feel less like watching a clock: working through our hospital bag checklist by week 36, finishing up any nursery projects earlier than you think you need to, and keeping track of your baby’s movements so you notice if their usual pattern changes. Our labor checklist is worth a look too, so you’re not reading it for the first time between contractions. Time spent on those tends to pass faster than time spent refreshing this page.
