How Is Your Age Calculated?
Most people think of age as simply the number of years since birth. But precise age calculation involves accounting for leap years, varying month lengths, and even daylight saving time for hour-level accuracy.
For legal, medical, and official purposes, your age on a specific date matters enormously. A child turning 18 on the last day of the year has very different rights than one born on the first day. AgeWise handles all these edge cases automatically.
In different cultures, age counting varies too. Some East Asian cultures count age from the moment of conception, making newborns "1 year old" at birth. Our calculator uses the Western convention of counting from the birth date.
