Age Calculator
Calculate Your Age, Life Expectancy & More with Our Free Online Tools!
Our free age calculator uses the most common age system, where your age increases on your birthday. For example, if you’re 3 years and 11 months old, your age is still 3. Only after your next birthday does it become 4. This system is standard in Western countries and is easy to understand.
But did you know? Other cultures calculate age differently. In traditional Chinese systems, babies start at age 1 (not 0), and their age increases on the Chinese New Year, not their birthday. For example, a baby born one day before the New Year turns 2 years old just two days later! Some cultures also count the current year in age, meaning a 20-year-old might be in their 21st year of life.
Our calculator avoids confusion by sticking to the birthday-based system. However, date calculations can sometimes seem tricky. For instance, from February 28 to March 31, is it one month or one month and 3 days? We use the day-to-day method (Feb. 28 → March 28 = 1 month, plus 3 days) for precision.
