Work out an exact age in years, months and days — handy for checking a job posting's min/max age rule.
Set "Date of birth" to your DOB and "As of date" to the closing date (or test/interview date) stated in the job advertisement — the exact years/months/days breakdown is what's compared against the posted age bracket.
It's a calendar breakdown of the gap between the two dates, not just total days converted — years and months are counted the way a birthday count normally works, so a partial month correctly borrows days from the previous month.
Below the main Y/M/D result, the calculator also converts the exact same span into total months, weeks, days, hours, minutes and seconds — useful if an age rule or form specifically asks for one of those units instead.
