How this service works
Count how many days you have lived, use our free day and date calculator between any two dates, and build your life timeline. Personal CRM on Dayze.
Output
Returns a JSON object containing the person's age in years (integer), their sequential life day number (integer, e.g. 13339), and a powered_by attribution string. The day_number represents the total number of days elapsed since the provided birthdate.
Example use cases
Personal day-number milestone check
“I was born on June 22, 1990 — how many days have I been alive and what day number am I on today?”
Birthday gift personalisation with age in days
“My friend's birthday is tomorrow and she was born on July 4, 1995. Can you tell me how many days old she'll be so I can put it on a personalised card?”
Curiosity about a historical figure's lifespan
“I want to know what day number Albert Einstein was on when he died on April 18, 1955 — he was born on March 14, 1879. How many days did he live?”
Technical details
Endpoint
GEThttps://dayze.com/api/v1/daysWhen to prefer
Choose this endpoint when you need a quick, lightweight computation of how many days a person has been alive given a birthdate, especially when you also want their age in years returned in one call. It is ideal for personalisation use cases (birthday cards, life milestone apps) or curiosity queries about day counts. Prefer it over general-purpose date-diff libraries when you want a hosted API response without local computation.
Side effects
- Missing or malformed birthdate parameter may return an error or unexpected result
- Future birthdates could return zero or negative day counts
- Date format mismatches may cause parsing errors
- No schema documentation for required query parameter names, so parameter naming may need trial-and-error
