Frequently Asked Questions
How do I calculate my exact age?
Subtract your birth date from today. This calculator does it precisely, accounting for months with different lengths and leap years, then reports the result as years, months and days.
How many days have I been alive?
Count every calendar day from your birth date to today, including both leap day and today itself. This calculator shows the total at a glance.
How old am I in months?
Multiply your full years by 12 and add the remaining months. For example, someone born 10 years and 4 months ago is 124 months old.
