Worked example
Born June 15, 1990
Someone born on June 15, 1990 checking on October 9, 2026 is 36 years, 3 months, and 24 days old — over 13,260 days lived. The math handles leap years and month lengths correctly, which is where manual counting always goes wrong.
Frequently asked questions
How is exact age calculated?
By comparing your birth date to today's date: full years first, then remaining months, then remaining days — carefully accounting for leap years and months of different lengths.
Why do forms ask for age in days or months?
Babies' ages are tracked in months because development moves fast. Some legal, medical, and insurance forms need precision beyond whole years.
Does the calculator handle leap years?
Yes — including February 29 birthdays. Leap-day babies get their correct age whether or not the current year is a leap year.
Can I calculate someone else's age?
Of course — enter any birth date. Handy for planning surprise parties or checking age cutoffs for school enrollment.
