Age Calculator

Enter your date of birth and the tool calculates your exact age in years, months, and days. It also shows total days, hours, and minutes alive, your zodiac sign, next birthday countdown with a visual progress ring, and generation classification.

The donut chart displays a visual countdown to your next birthday with the number of days remaining in the center. The ring fills as your birthday approaches, making it easy to see at a glance how close your next celebration is.

The milestone timeline tracks events like your 1,000th day alive, 10,000th day, 100,000th hour, 1 billionth second, and upcoming round birthdays. Past milestones show their dates, and future ones show how many days remain.

Korean counting age starts at 1 at birth and increases by 1 every New Year's Day, regardless of your actual birthday. The calculator shows both international age and Korean counting age for comparison.
