Delivery Date Calculator: How to Estimate Your Due Date

📅 Introduction: Why Knowing Your Due Date Matters

As soon as you discover you're pregnant, one of the first questions you may ask is: "When will my baby arrive?"Knowing your estimated due date helps you plan prenatal care, nutrition, lifestyle, and delivery preparation. That’s where a delivery date calculator becomes essential.

🤔 What Is a Delivery Date Calculator?

A delivery date calculator estimates when your baby is likely to be born. It uses the first day of your last menstrual period (LMP) or your ovulation date to project your due date—typically 40 weeks from the start of your last cycle.

🧮 How Is the Due Date Calculated?

1. Based on Last Menstrual Period (LMP):

• Formula: LMP + 280 days (40 weeks)

• Most common method used by doctors

  
  

2. Based on Ovulation/Conception Date:

• Used if you track your ovulation or had IVF

• Formula: Ovulation date + 266 days

  
  

3. By Ultrasound Scan:

• Done in the first trimester to measure fetal size

• More accurate if LMP is unknown or cycles are irregular
