Baby countdown
See the days, weeks and little landmarks between today and your estimated due date.
Direct answer: enter your estimated due date to subtract today and see the exact number of calendar days left. The progress view maps that date onto the conventional 280-day pregnancy timeline.
Use the official estimated due date recorded by your care team when you have one. Your date stays in this browser.
Add your estimated due date to start the countdown.
A countdown to an estimate, not a deadline
A due date is useful for planning care and making the months ahead tangible, but it is not a guaranteed birthday. ACOG explains that the average pregnancy is counted as 280 days, or 40 weeks, from the first day of the last menstrual period.
Read ACOG's guidance about due dates and pregnancies that go past them, and keep the official date documented by your maternity-care professional.
Common questions
How many days are left until my baby is due?
Enter your estimated due date and the countdown subtracts today's date. It also shows complete weeks plus remaining days and progress through a conventional 40-week pregnancy calendar.
How accurate is a due-date countdown?
The countdown arithmetic is exact, but the due date itself is an estimate. ACOG describes the average pregnancy as 280 days from the first day of the last menstrual period; actual birth timing varies.
What happens if my due date passes?
The tool switches to days since the estimated due date. Contact your maternity-care professional and follow their monitoring or care plan rather than relying on a countdown.
Should I use my LMP date or ultrasound due date?
Use the estimated due date documented by your care team. ACOG says first-trimester ultrasound is the most accurate method to establish or confirm gestational age.
