Boundary set by researchers or the birth record Named by a writer or a consultancy, or claimed by two sources; the dates are not settled

Only the baby boom has an official definition, taken from the birth rate. Everything after Generation Z, and everything before the Silent Generation, is a label somebody proposed. McCrindle starts Generation Alpha in 2010, before Pew ends Generation Z in 2012, so those three years belong to both. As at 2026.

The Chinese year, and the date it actually began

Chinese New Year 1921 fell on 8 February 1921, the start of the year of the Metal Rooster. Anyone born in 1921 before that date belongs to the previous Chinese year — the year of the Metal Monkey, not the Rooster.
