Due Date Calculator: Your Essential Tool for Pregnancy Planning
Pregnancy is one of life’s most transformative journeys, filled with anticipation and countless questions. At the heart of this experience lies a fundamental question: “When will my baby arrive?” This is where a due date calculator becomes an indispensable tool for expectant parents. At GoodTechReview, we’ve developed an advanced pregnancy calculator that takes the guesswork out of this crucial calculation while providing valuable insights about your pregnancy journey.
How Due Date Calculators Work
Most pregnancies last approximately 40 weeks from the first day of your last menstrual period (LMP). Our algorithm uses two primary calculation methods:
- LMP Method: Adds 280 days (40 weeks) to your last menstrual period start date
- Conception Date Method: Adds 266 days (38 weeks) to the known conception date
These calculations follow Naegele’s Rule, the standard obstetric formula used by healthcare professionals worldwide. While every pregnancy is unique, this method provides a reliable estimation window for prenatal planning.
Beyond the Due Date: Comprehensive Pregnancy Insights
Modern due date calculators like GoodTechReview’s solution offer far more than just a target date. Our tool provides:
- Gestational age tracking: See your current progress in weeks and days
- Trimester breakdown: Understand which pregnancy phase you’re in
- Progress visualization: A visual progress bar showing completion percentage
- Days remaining countdown: Know exactly how many days until your due date
- Trimester-specific information: Relevant details for each pregnancy stage
Why Accuracy Matters in Pregnancy Dating
Accurate due date calculation impacts crucial medical decisions:
- Scheduling prenatal screenings and diagnostic tests
- Determining fetal growth milestones
- Identifying potential preterm labor risks
- Planning maternity leave and baby preparations
While our calculator provides medical-grade calculations, we always recommend confirming results with your obstetrician or midwife, as individual factors like menstrual cycle regularity and ultrasound measurements can influence your official due date.

Frequently Asked Questions (FAQs)
1. How accurate is GoodTechReview’s due date calculator?
Our calculator uses the same medical formula (Naegele’s Rule) that healthcare providers use, making it as accurate as clinical estimations. However, only 5% of babies arrive exactly on their due date; consider it an estimated delivery window between 38 and 42 weeks.
2. Can I use the calculator if I have irregular periods?
Yes, but for greatest accuracy, use the conception date method if known. Women with irregular cycles should consult their OB-GYN, who may adjust dates based on early ultrasound measurements.
3. Does the calculator work for IVF pregnancies?
Absolutely! For IVF pregnancies, use your embryo transfer date as the conception date. Add 266 days for day-5 blastocyst transfers or 263 days for day-3 transfers to calculate your due date.
4. Why does my doctor’s due date differ slightly from calculator results?
Healthcare providers may adjust dates based on early ultrasound measurements, which are most accurate between 8 and 13 weeks. Fundal height measurements and fetal development observations in later pregnancy may also prompt date adjustments.
5. Can I calculate my due date without knowing my LMP or conception date?
While exact dates provide the most accurate results, you can estimate based on early pregnancy symptoms or fertility tracking. However, we recommend consulting your healthcare provider for clinical dating via ultrasound if dates are uncertain.
