Generation Calculator
Find which generation a birth year belongs to.
Boomer, millennial, Gen Z and the rest
Birth years are commonly grouped into named generations — from the baby boomers through Generation X, millennials, Generation Z and beyond. This finds which generation a birth year falls into, along with the rough range that defines it.

Useful shorthand, blurry edges
Generational labels are a useful shorthand for talking about the broad experiences shared by people who grew up in the same era — the technology, events and culture that shaped a cohort. But it is worth holding them loosely, because the boundaries are approximate and disputed: different sources draw the cutoffs in slightly different years, so someone born near an edge might be classed either way, and the labels describe broad tendencies, not individuals. Someone's generation says little for certain about them personally. Treated as a rough cultural marker and a bit of fun, generational labels are interesting; treated as a firm category that determines what someone is like, they mislead. The named generations are a lens on shared history, best used lightly.
