Enter a birth year to see the strict generation boundary, cusper status, adjacent cohort, milestone years, and the cultural artifacts people use to argue about it.
Millennials
Born 1981-1996. You are 30 years old in 2026.
Millennials were raised during the internet's arrival and reached adulthood through 9/11, social media, and the 2008 crash. They are the last cohort with a strong memory of both offline childhood and always-online adulthood.
Adjacent generation
Cusper years often borrow language from both sides. Compare those artifacts with Gen Z: iPhone childhood, TikTok, Snapchat, Instagram Stories.

Generation labels look tidy in a table, but the edges carry real status arguments. A 1996 birth year is usually Millennial in Pew-style boundaries; a 1997 birth year is usually Gen Z. That one-year split changes which recession, phone, school internet, and social-media story people think shaped you.
Cuspers sit within two years of a boundary, so their childhood artifacts often belong to one cohort while their teen or workplace references belong to another. Xennials, Zillennials, Zalphas, and Alpha-Beta cusp kids are useful shorthand, not formal census boxes.
Gen Beta starts in 2025 in this table and runs through 2039. In 2026, its oldest members are still toddlers, so the name is search-first and culturally unresolved: AI toys, ambient assistants, climate adaptation, and whatever becomes normal before they remember it.
