How the answer is worked out
Subtract your birth year from the current year: 2026 − 1984 = 42. That is your age once your birthday has passed this year. Until then you are one year younger, 41. For example, someone born in March 1984 is 42 from March onward, while someone born in November 1984 stays 41 until their November birthday.
What generation is 1984?
People born in 1984 belong to the Millennials (Generation Y). The Pew Research Center, whose definitions are the most widely used in the US, places this generation from 1981 to 1996. Generation boundaries are conventions rather than strict rules, so you may also see slightly different ranges elsewhere.
Chinese zodiac for 1984
1984 is the Year of the Rat. The Chinese zodiac follows the lunar calendar, and Lunar New Year falls in late January or February. If you were born in January or early February 1984, before that year’s Lunar New Year, your sign is the Pig instead.
