This tool will calculate the gestational age based on the date of your last menstrual period.
How to Use the Gestational Age Calculator
To use the gestational age calculator, follow these steps:
- Enter the first day of your last menstrual period in the format MM/DD/YYYY.
- Enter your average cycle length in days. The typical cycle length is 28 days, but if your cycle is longer or shorter, adjust accordingly.
- Click on the “Calculate” button to get the results.
How it Calculates Results
The calculator first converts your provided last menstrual period (LMP) date to a Date object. It then adjusts this date if your cycle length differs from the standard 28 days. Next, it calculates the number of days that have passed since your adjusted LMP date to determine the gestational age. Finally, it adds 280 days to the adjusted LMP date to estimate the due date.
Limitations
This tool provides an estimate based on the information you provide. Actual gestational age and due date may vary based on various factors such as cycle irregularities, conception date, and ultrasound measurements. Always consult with your healthcare provider for more accurate and personalized information.
