How the math works
The calculator counts full years first, then full months, then the leftover days, borrowing days from the month before the "age at" date when the day count goes negative. Someone born June 15, 1990 is 36 years, 4 months and 9 days old on October 24, 2026.
The next birthday is the next time the birth month and day come around. If the "age at" date is the birthday itself, the next birthday shown is today. Leave the second date alone to calculate the age as of today.
