Frequently Asked Questions
How is exact age calculated?
Exact age is calculated by counting the full years, months, and days from your birthdate to today. It accounts for varying month lengths and leap years to give a precise result.
What is a leap year and how does it affect age?
A leap year has 366 days instead of 365, with February having 29 days. Leap years occur every 4 years (except century years not divisible by 400). If you were born on Feb 29, your birthday technically occurs once every 4 years, though most celebrate on Feb 28 or Mar 1.
How do different cultures calculate age?
In most Western countries, age starts at 0 at birth. In traditional East Asian age counting (used in Korea until 2023), a person is 1 at birth and gains a year every January 1st. Some cultures also use lunar calendars for age calculation.
