What is a corrected age calculator used for?

It supports preterm workflows where age interpretation needs adjustment for weeks born early.

Is corrected age the same as chronological age?

No. Chronological age is time since birth, while corrected age adjusts that value for prematurity.

Where can I compare both methods?

Use the comparison and premature-focused pages linked below to document the right age basis.
