Calculate Corrected ASQ Age Instantly

ASQ Age Calculator. If your baby was born early (before 37 weeks), it’s important to use their corrected age when filling out ASQ forms. This helps you find the right form based on your baby’s development not just their birth date.

Parent using ASQ age calculator to check corrected age for developmental milestones

Let’s learn how to do this in a very simple way.

What Is Corrected Age?

Corrected age means your baby’s age if they were born on their due date, not their actual birth date.

Example:

  • Your baby is 12 weeks old today (this is called chronological age).

  • They were born 4 weeks early.

  • So their corrected age is:
    👉 12 weeks – 4 weeks = 8 weeks

Using corrected age helps you see where your baby is in development and which ASQ form to use.

How to Calculate Corrected Age?

It’s super easy! Just follow these 3 steps:

  1. Check baby’s birth date

  2. Find how many weeks early they were
    (Full term is 40 weeks, so subtract the gestational age at birth)

  3. Subtract those weeks from their current age

Another Example:

  • Born at 32 weeks (that’s 8 weeks early)

  • Today they are 20 weeks old

  • Corrected Age = 20 – 8 = 12 weeks

If that’s confusing, don’t worry! You can use this guide:
🔗 How to Calculate Age from Date of Birth Manually

Or use Excel if you’re a bit technical:

Why Is Corrected Age Important for ASQ?

ASQ forms are made for specific age groups like 2 months, 4 months, 6 months, etc.

If your baby was born early and you don’t use the corrected age, you might choose the wrong form and get results that don’t match their actual development.

Using corrected age helps you:

  • Pick the right ASQ form

  • Understand your baby’s real progress

  • Avoid stress or worry about low scores

Until When Should I Use Corrected Age?

Doctors recommend using corrected age until your child is 24 months old. After that, you can use their real (chronological) age for everything.

Final Tip ASQ Age Calculator

Always remember, every baby grows at their own pace. If your baby was born early, that’s okay! Corrected age helps you measure progress the right way.
