Corrected Age Calculator

Using the Corrected Age Calculator

Step 1: Gather Required Information

Before using the Corrected Age Calculator, ensure you have the following information ready:

• Birth Date: The birth date of the individual you are calculating the corrected age for. Ensure the date is on or before December 31, 2024.
• Gestational Age at Birth (Weeks): The number of full weeks at gestation when the individual was born. This should be between 23 and 42 weeks.
• Additional Days: Any additional days at gestation beyond the full weeks. This should be between 0 and 6 days.

Step 2: Enter Information into the Calculator

Open the Corrected Age Calculator interface and fill in the required fields:

• Birth Date: Input the individual’s birth date using the date selector or type it in the format YYYY-MM-DD.
• Gestational Age at Birth (Weeks): Input the number of weeks using the number field. This represents the full weeks of gestation.
• Additional Days: Input any additional gestational days using the number field. This supplements the full gestational weeks.

Step 3: Review the Calculated Results

Once you have entered all the required information, the calculator will automatically compute the following results:

• Chronological Age: Displays the age in years between the birth date and today’s date, with precision to one decimal place.
• Born at: Indicates the gestational age in weeks, combining both the weeks and additional days, rounded to one decimal place.
• Weeks Early: Shows how many weeks early the birth was compared to a full-term 40-week gestation, calculated and displayed in weeks to one decimal place.
• Corrected Age: Provides the age adjusted for prematurity by subtracting the weeks early from the chronological age, expressed in years to one decimal place.

Step 4: Interpret the Results

Use the results to understand the growth and development context of the individual compared to their chronological age. For example, the corrected age is often used in developmental assessments to compare premature infants more accurately against standard growth milestones.

If any of the input requirements or calculations are unclear, consider consulting healthcare professionals to ensure the accuracy of your data and interpretations.
