How this service works
Age calculator from birthdate - exact age in years, months and days, total days lived and days until the next birthday
Output
Returns a JSON object containing: the exact age broken down into years, months, and days; the total number of days lived; the date of the next birthday; the number of days until the next birthday; the day of the week the person was born; the reference date used for calculations; and the timestamp when the check was run.
Example use cases
Birthday milestone celebration planning
“My friend was born on July 4, 1985 — can you tell me exactly how old they'll be this year, what day of the week they were born, and how many days until their next birthday?”
Age verification for a form
“A user entered their date of birth as 2001-09-11 — what is their exact age today in years, months, and days so I can confirm they're over 18?”
Historical age at a past date
“How old was someone born on 1955-06-14 on the date 2000-01-01? I need the exact breakdown in years, months, and days.”

Endpoint
GEThttps://saylorinnovations.com/api/calc/age?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a precise, multi-component age breakdown (years, months, days) from a birthdate, especially when you also need total days lived, next birthday date, or days-until-next-birthday in a single call. Prefer it over manual date arithmetic or generic date libraries when building agent workflows that require structured, ready-to-use age data with optional reference-date support.
Side effects
- Missing required 'birthdate' parameter returns an error
- Incorrectly formatted date (not YYYY-MM-DD) may cause a parsing error or unexpected result
- Future birthdates may produce zero or negative ages
- Invalid calendar dates (e.g. February 30) may cause errors
- Reference date ('on') in wrong format may default to today or return an error
