Enter your date of birth to calculate your exact age
Age is calculated by counting the years, months, and days between your birth date and the reference date. Leap years (366 days) are automatically accounted for, ensuring accuracy across all dates.
Western zodiac signs are determined by your birth date (e.g., Aries: Mar 21–Apr 19, Taurus: Apr 20–May 20). Chinese zodiac is determined by birth year in a 12-year cycle. Both systems assign personality traits to date ranges.
In most Western countries, age increases on each birthday. In East Asian cultures (especially Korea), age is counted differently — you're 1 at birth and gain a year each January 1st. This calculator uses the Western standard.
