Our adjusted age calculator allows you to calculate the corrected age of your newborn baby quickly and easily. This tool is designed for babies born preterm, that is between the 21st and the 37th week of gestation.
Read on to discover why it is so important to know the adjusted age for prematurity and find out how to correctly use our premature age calculator.
🍼 We'll also talk about details and differences in care for babies born before the 37th week of their gestation.
Why do we need the adjusted age calculator for prematurity?
We need to know the adjusted age of a baby to correctly assess its development and milestones. If we didn't use the corrected gestational age calculator, we could draw the false conclusion that the baby is not developing properly, which may lead to the application of unnecessary or even harmful treatments. You should always inform your pediatrician that your baby was born preterm.
After your baby's adjusted age is 24-months, you should start using their chronological age instead.

Your results are here!
- You will receive the value of both your baby's chronological and adjusted age for prematurity; and
- If you've just welcomed your baby into the world, the calculator will tell you the exact moment you should start counting its adjusted age.
Premature birth is often associated with a medical intervention - check your probability of a vaginal delivery after a C-section.
How to calculate the preemie adjusted age?
Calculating the adjusted age is not as difficult as it seems - try it out!
Our corrected age calculator uses the following equations:
Chronological age = (Current date - Birth date) - your baby's official age.
Gestational age method:
Age difference = Full term (280 days) - Gestational age at the time of birth (in days)
Due date method:
Age difference = Due date - Birth date
|💡 Human pregnancy takes 40 weeks, that is 280 days. If the baby was born few days before or after that date, we say that the pregnancy was full term.|
Adjusted age = Chronological age - Age difference
A word on premature babies
The preterm baby is a child that was born before the 37th week of the pregnancy. A baby can be extremely (<8 wks), very (<32 wks), or moderately preterm (<37 wks). Before the delivery, the future mother should be given corticosteroids to speed up the baby's lung development - babies born very preterm may have problems taking their first breath.
|🌟 The youngest premature baby was born after only 21 weeks and 4 days of the pregnancy and weighed 0.9 lb (410 g) - that's less than the weight of the official NFL football (0.93 lb, 430 g)!|
Every newborn baby must be assessed using the Apgar score. The higher the score, the better the result. Preterm babies tend to receive lower scores since their bodies are not fully adapted for the outside world - they usually need full medical attention.
Due to extremely small size of preterm babies and how this impacts their head circumferences, medical staff needs unique methods and equipment to take care of their tiny patients. For example, blood samples are usually taken from the baby's heel.
Due to the structures called fontanelles a physician can take a look into the baby's head using an ultrasound - it's a safe, non-invasive and painless test.
Preterm-born babies have prolonged hyperbilirubinemia of newborns, and are at greater risk of complications due to it.
