Every birth year

107 years, 1920 to 2026. Each has its generation, its Chinese animal and element with the real lunar new year date, and how old that year's cohort turns during 2026.

In the United States only one generation has an official definition: the baby boom, which the Census Bureau puts at 1946 to 1964. The years used for the Silent Generation, Generation X, the Millennials and Generation Z are Pew Research Center's; Generation Alpha and Generation Beta, names and years both, come from McCrindle, an Australian research firm. McCrindle starts Alpha in 2010 while Pew runs Z to 2012, so the pages for those three years give both answers. Each decade has a written page too, on the world its children were born into.
