Frequently Asked Questions
How do I calculate my exact age?
Your chronological age is calculated by subtracting your birth year from the current year. If your birthday has not occurred yet this calendar year, you are one year younger than the raw subtraction.
What generational cohorts exist today?
Demographers generally classify generations as: Generation Alpha (2013–mid-2020s), Generation Z (1997–2012), Millennials (1981–1996), Generation X (1965–1980), Baby Boomers (1946–1964), and the Silent Generation (1928–1945).
What are the major milestone birthdays?
Common milestone birthdays include 16 (driving age in the US), 18 (legal voting & adulthood), 21 (full majority), 30 (decade milestone), 50 (golden half-century), 65 (traditional retirement age), and 100 (centenarian).
