Millennial birth years
Millennials (sometimes Generation Y) grew up as personal computing and the early internet became ordinary, then entered adulthood around the turn of the millennium.
Pew Research Center treats 1981 to 1996 as its Millennial birth years. That decision keeps the cohort a usable length for surveys as people age.

How this differs from calendar math
Your weekday of birth and age in days are fixed once the date is known. A generation label is a shared nickname for a band of years. Prefer the methodology page when you want the full factual-versus-label map.

Common questions
Which birth years count as Millennial here?
This site maps Millennial to 1981 to 1996. Researchers sometimes shift the edges by a few years.
Who decides generation names?
There is no single worldwide authority. Pollsters, historians, and marketers popularize ranges; Pew Research Center is a widely cited U.S. reference for several modern cohorts.
Is a generation the same as my Chinese zodiac year?
No. Generation labels group many birth years for social commentary. Chinese zodiac animals change each lunar New Year.
