You share your birthday with these notable people!
Your age is calculated by counting the number of complete years between your birth date and today's date. The calculator accounts for the exact day, month, and year, so your age only increases on your actual birthday each year.
If you were born on February 29, your birthday officially occurs only every four years. In non-leap years, most countries and calculators recognize either February 28 or March 1 as your legal birthday, depending on local convention.
Exact age counts complete years, months, and days since your birth date, while approximate age simply states the number of full years. For example, someone born 30 years and 8 months ago has an exact age of 30 years and 8 months, but an approximate age of 30.
Time zone can matter if you were born very close to midnight. If you were born at 11:30 PM in one time zone, someone calculating your age from a different time zone might count an extra day. For most purposes, the date alone is sufficient for age calculation.
A birthday is the anniversary of the day you were born. Legally and culturally, your birthday marks the date you complete another full year of life. In most jurisdictions, you are considered to reach a new age at the very start of your birthday.
