Frequently Asked Questions
Your age is calculated by finding the difference between today date and your date of birth in years, months and days. Leap years and varying month lengths are all accounted for so the result is always precise.
In the UK you can drive at 17, vote at 18, stand for Parliament at 18, drink alcohol at 18, rent a car at 21, and run for Prime Minister with no upper age limit. Our calculator shows your personalised milestone dates.
Because each planet takes a different amount of time to orbit the Sun, your age in Earth years translates to a very different age on other planets. On Mercury a year is just 88 Earth days, so you would be much older. On Neptune a year is 165 Earth years, so most people have not completed one Neptunian year.
Generations are roughly defined as: Silent Generation (born before 1945), Baby Boomers (1946-1964), Generation X (1965-1980), Millennials (1981-1996), Generation Z (1997-2012) and Generation Alpha (2013 onwards).
