Pregnancy Due Date Calculator – Estimate Your Baby’s Arrival
Tracking your pregnancy due date helps you prepare for your baby’s arrival. Our Pregnancy Due Date Calculator estimates your expected due date based on the first day of your last menstrual period (LMP) or date of conception.
How the Pregnancy Due Date Calculator Works
A full-term pregnancy lasts about 40 weeks (280 days) from the first day of your last menstrual period (LMP). The calculator uses two common methods:
1. Last Menstrual Period (LMP) Method (Most Common)
- Formula: LMP + 280 days (40 weeks)
- Example:
- LMP: January 1, 2025
- Estimated Due Date: October 7, 2025
2. Conception Date Method
- Formula: Date of Conception + 266 days (38 weeks)
- Example:
- Conception Date: January 15, 2025
- Estimated Due Date: October 7, 2025
Using the Pregnancy Due Date Calculator
- Enter your LMP date or conception date.
- The calculator will estimate your due date instantly.
- Monitor each trimester for key milestones.
Understanding Pregnancy Trimesters
| Trimester | Weeks | Key Developments |
|---|---|---|
| First | 1 – 12 | Early fetal development, nausea, fatigue |
| Second | 13 – 27 | Baby’s movement felt, reduced nausea |
| Third | 28 – 40 | Rapid growth, baby prepares for birth |
What Affects Your Due Date?
- Irregular periods may shift your due date.
- Ultrasounds can confirm fetal growth and adjust the estimated date.
- Multiples (twins, triplets, etc.) may result in earlier delivery.
