Pregnancy Due Date & Week Tracker

Skip the guesswork and the ten different apps asking for your email. This calculator gives you your due date, current week, trimester, and days remaining the moment you enter one date.

How it works:

• Choose either your last period date or your conception date

• Adjust for your average cycle length if it’s not exactly 28 days

• Get your estimated due date instantly, calculated the same way most OBs do it

• See your current week, trimester, and a visual progress bar toward week 40

• Read a plain-language summary of what’s typical for your current trimester

What’s included:

• One HTML calculator file — download it, open it in any browser (phone, laptop, tablet), and revisit it anytime

• No wifi needed after download, no login, no subscription

• Recalculate instantly if your provider gives you an updated due date

This is a general estimate, not medical advice — your OB or midwife’s dating, especially from an early ultrasound, is more accurate than any calculator.
