Preemie Adjusted Age Calculator
Calculate the corrected age for premature babies. Enter the birth date and due date to get chronological and adjusted age for developmental tracking.
Preemie Adjusted Age Calculator
If a baby is born prematurely, developmental milestones—like crawling or smiling—should be tracked using Adjusted Age. This is the age the baby would be if they were born on their original due date. This prevents parents from worrying about "delays" that are actually biologically on track.
For example, if a 6-month-old was born 2 months early, their adjusted age is 4 months. Use this tool until your child reaches age 2, then switch to the Standard Age Calculator. You can also find their very first Half-Birthday using their actual birth date for celebration.
How to Use
- Enter the baby's actual date of birth.
- Enter the original due date (EDD).
- The tool shows both chronological age and adjusted age for accurate developmental tracking.
Frequently Asked Questions
Got questions about adjusted age? We've got answers.
When do I stop adjusting?
Most experts recommend using adjusted age until the child reaches two years of age.
Why is adjusted age important?
It provides a realistic developmental baseline. A 6-month-old born 2 months early has an adjusted age of 4 months — their development should match a 4-month-old.
Do I use adjusted age for vaccines?
No. Vaccines are typically given based on chronological (actual) age, not adjusted age.
