Calculate the adjusted age of a premature baby in weeks and months relative to the due date.
The adjusted age calculator calculates the age of a premature baby by taking into account how much earlier they were born compared to the due date. Development is usually compared to adjusted age rather than chronological age.
The calculator is free, works in your browser without registration, and shows the result as soon as you change the values. The calculation is done on your device, and the information you enter is not sent anywhere.
Prematurity (weeks) = 40 − weeks of gestation at birth. Adjusted age = time since birth − prematurity.
The baby was born at 32 weeks of gestation, so they were 8 weeks premature. When 36 weeks have passed since birth, the adjusted age is 28 weeks or about 6.5 months. With default settings, the calculator gives the result: Adjusted age 6.3 months.
Parents and relatives of premature babies who want to know what age to compare the child’s development to.
Generally until about two years of age. The health clinic provides more specific guidance.
The development of a premature baby progresses relative to the due date, so comparing to chronological age would give a misleading picture.
No. The calculator is indicative, and the health clinic makes the assessment of development.
