2024-10-07 00:00:00 An app designed with Intervention Specialists in mind, EI Age Calculator allows you to quickly and easily calculate how many months old a child is for Early Intervention. This app does not store any PII and calculates ages in years, months, and days, making it the prefect tool for quick developmental progress checks without worrying about violating any privacy laws. While designed with Early Intervention Specialists in mind, this app can also be used to calculate the age of anyone born in the common era for reasons other than EI.
