Designed for clinicians, this is the most flexible gestational age calculator available, ideal for obstetricians, neonatologists, and pediatricians. Enter any available dates, ages, or gestations, and other values will be calculated.

Example use cases:

• for obstetricians, enter the date of the last menstrual period, and the due date will be calculated. By default, the current gestational age will also be displayed.

• for neonatologists, enter the due date and the date of birth, and the gestation at birth will be calculated. A date of interest can also be entered (defaults to current date), and the age and postmenstrual age will also be displayed. Also, the date of the initial exam for retinopathy of prematurity is shown.

• for pediatricians, entering the date of birth, gestational age at birth, and current date will yield the chronologic age and age corrected for prematurity. Ideal for developmental pediatricians to assess milestone acquisition.
