Millennials are generally defined as people born between 1981 and 1996, which means they are roughly in their late 20s to mid‑40s today (about 29–44 years old in 2025).

Millennial age in 2026

Using the widely accepted 1981–1996 birth-year definition for millennials:

  • Oldest millennials (born 1981): about 45 years old in 2026.
  • Youngest millennials (born 1996): about 30 years old in 2026.

So in 2026, millennials are roughly 30–45 years old.

Where this definition comes from

Several major references and organizations describe millennials as those born 1981–1996 (sometimes allowing a year or two of variation):

  • Encyclopaedia Britannica defines millennials as born 1981–1996.
  • Many demographic and HR sources use 1981–1996 and give a 29–44 age range for 2025.
  • Wikipedia notes 1981–1996 as a “widely accepted” millennial cohort.

Some commentators or forum users stretch the range slightly (for example, 1981–1999 or 1982–1996), but 1981–1996 is now the most commonly used bracket.

TL;DR: If you’re between about 30 and 45 years old in 2026 and were born from 1981 to 1996, you’re generally considered a millennial.
