Calculate your exact age down to the second
Calculating your exact age is more than just subtracting your birth year from the current year. Your precise age depends on whether your birthday has occurred yet this year, and to get an exact figure down to the day, you need to account for varying month lengths and leap years.
Our calculator determines your age by computing the difference between your date of birth and today's date. It accounts for months with different numbers of days (28, 29, 30, or 31) and correctly handles leap years. The result gives you your exact age broken down into years, months, and days.
To find your age in days, the calculator counts every single day from your birth date to today, including leap days. For example, someone born on January 1, 1990 has lived through over 13,000 days. This number includes 9 leap days (from 1992, 1996, 2000, 2004, 2008, 2012, 2016, 2020, and 2024).
Ever wondered what day of the week you were born? Our age calculator tells you that too. Studies have shown that more babies are born on Tuesdays than any other day, while weekends see fewer births due to fewer scheduled deliveries and C-sections.
Your zodiac sign is determined by the position of the sun on your date of birth. There are 12 Western zodiac signs, each spanning roughly one month. Our calculator automatically determines both your Western zodiac sign and your Chinese zodiac animal based on your birth year.
