Know the age. See the dates. Keep the context.
Use an exact calendar age, corrected age for prematurity, the next CDC checklist age and dates from a published vaccination schedule — without creating an account.
Step one
Child age calculator
This calculator runs in the page. It does not create a child profile or store the date you enter.
Step two
Vaccination date planner
Dates appear after the age is known
Enter a date of birth to apply every published schedule age deterministically.
How to use the result
A planner for preparation, never a prescription
The useful part is arriving at a visit with dates and questions organised. The clinical decision still belongs to the qualified professional caring for the child.
Check the child's card
The planner does not know which doses were already administered. Compare it with the actual vaccination card.
Use corrected age carefully
Corrected age is displayed for context when a child was born before 37 completed weeks; each clinical decision still needs professional judgement.
Save the real record
Create an AVYOMI profile to keep measurements, observations, documents and administered doses together over time.
