Your baby is developing rapidly and you couldn’t be more thrilled. Amidst the excitement and wonder of pregnancy, there’s one question that captivates your thoughts: “When will my baby arrive?” As expectant parents, it’s only natural to be eager to know the due date- the day your baby arrives. We’ve built a tool based on Naegele’s rule that can put a stop to your question. In this article, let’s see how this rule works and how you can make use of Naegele’s Rule Calculator [Due Date].
What is the Naegele’s Rule Calculator [Due Date]
The Naegele’s Rule Calculator is a tool designed to estimate the expected date of delivery (EDD) of a pregnancy. Named after the renowned German obstetrician Franz Karl Naegele, the calculator employs a simple formula he proposed in 1830.
Following this rule, the calculator calculates your due date using the LMP (Last Menstrual Period) data you provide. The result, which includes a due date, tells you an approximate idea of when your child will be delivered. That’s good news for expecting parents because it makes estimating the due date quick and easy.
What is the Naegele’s Rule?
The Naegele’s rule is a formula that has been grounded over time and it’s used to estimate a pregnancy’s due date. The rule is based on the general assumption that a full-term pregnancy lasts for 40 weeks or approximately 280 days from the last menstrual period (LMP).
Key points you should be aware of:
1. The Last Menstrual Period
The foundation of Naegele’s rule begins with pinpointing the first day of the last menstrual period. This date marks the starting point for calculating the estimated due date.
2. Subtract 3 Months
Another key point is counting three months backward during the calculation.
3. Adding 7 days
While calculating, the rule adds 7 days to discover your due date.
4. Adding a year
The calculator also adds a year to figure out your estimated due date.
With that understanding, let’s see how the calculation is done.

How Do You Calculate the Due Date Using Naegele’s Rule?
To calculate the due date using Naegele’s Rule, let’s take some examples for accurate illustration:
Example 1: If the first day of your LMP is January 2, 2023.
- Add 1 year- January 2, 2023, plus 1 year = January 2, 2024
- Subtract 3 months- January 2, 2024, – 3 months= October 2, 2023
- Add 7 days- September 2, 2023, + 7 days= October 9, 2023.
In this example, October 9, 2023, would be the estimated due date for your baby’s arrival.
Example 2: If the first day of your LMP is May 13, 2023
- Add 1 year- May 13, 2023, plus 1 year = May 13, 2024
- Subtract 3 months- May 13, 2024, – 3 months= February 13, 2024
- Add 7 days – February 13, 2024, + 7 days= February 20, 2024.
This means, your due date is February 20, 2024.
