How it works
Your age is the number of full years since you were born. Subtract your birth year from the current year, then take one away if your birthday has not happened yet this year. Generations follow the Pew Research Center’s ranges (the youngest are common usage), the Chinese zodiac year starts at Chinese New Year in late January or February, and the US full retirement age is set by the Social Security Administration by birth year.
