Week Pregnancy Calculator

Last Menstrual Period Date:

Calculate

 

Introduction

The Week Pregnancy Calculator is a valuable tool for expectant parents, allowing them to track and understand the progression of pregnancy with ease. This calculator provides an estimate of the current week of pregnancy based on the woman’s last menstrual period (LMP) or the conception date.

Formula:

The formula used by the Week Pregnancy Calculator is based on the gestational age, which is the time elapsed since the first day of the woman’s last menstrual period. The general formula is:

Gestational Age (in weeks)=⌈Current Date−LMP7⌉Gestational Age (in weeks)=⌈7Current Date−LMP​⌉

Here, the result is rounded up to the nearest whole number to represent the full weeks of pregnancy.

How to Use?

Using the Week Pregnancy Calculator is a straightforward process:

1. Enter Last Menstrual Period (LMP) or Conception Date: Input either the first day of the last menstrual period or the conception date, depending on the information available.
2. Calculate: Press the calculate button to obtain the estimated gestational age in weeks.

Example:

Let’s consider an example:

• LMP: January 1, 2023
• Current Date: May 1, 2023

Gestational Age (in weeks)=⌈May 1, 2023−January 1, 20237⌉Gestational Age (in weeks)=⌈7May 1, 2023−January 1, 2023​⌉

Gestational Age (in weeks)=⌈120 days7⌉=18 weeks Gestational Age (in weeks)=⌈7120 days​⌉=18 weeks

So, based on this example, the estimated gestational age is 18 weeks.
