Pregnancy Week Calculator: Weeks Today and Days to Due Date
Estimate how many weeks and days pregnant you are today and how many days remain until the due date. Start from last period (LMP plus 280 days) or enter a due date from your clinic. Calendar tracking only, not a medical diagnosis. Follow dates from ultrasound or maternity care when they differ.
How to use
Under Calculate based on, choose Last period start date or Due date. Enter the date. Results show Pregnancy week (weeks and days, e.g. 8 v, 5 d) and Days remaining with the linked estimated due date below. The page accepts roughly 0 to 300 days from LMP; outside that range it may show dashes. If due date mode is used, the tool derives LMP as due date minus 280 days for the week count.
Example
Last period 19 March often gives a due date near late December. If today is about eight weeks after LMP, you might see around 8 weeks and 5 days with roughly 219 days left. Most births happen within a few weeks of the due date, not always on that day.
Tips
Gestational age from LMP is usually about two weeks ahead of fetal age counted from conception. That is normal in maternity records. Contact your care provider for pain, bleeding, reduced fetal movement, fever, or other urgent concerns. Dates are not stored in a Calctivo account by default.
