Enter your date of birth into the birthday calculator and discover what day you were born on and how long you've been alive.
The calculated age will be displayed in years, months, weeks, days, hours, minutes, and seconds.
East Asian age reckoning originated in China and continues in limited use there along with Tibet and Japan, but is still common in Korea. People are born at the age of one, i.e. the first year of lifetime using ordinal number (instead of "zero" using cardinal number), and on Chinese New Year or New Year's Day one year is added to their age. Since age is incremented at the beginning of the lunar or solar year, rather than on the anniversary of a birthday, people may be one or two years older in Asian reckoning than in the international age system.
