How the age calculator works
The calculator counts full years first, then the remaining months, then the leftover days — the way people naturally describe age. It accounts for different month lengths and leap years, so the result is exact rather than an average. Change the second date to measure the gap between any two dates: an anniversary, a project deadline, or how long until an event.
