What are the generation year ranges?

WWII (1901–1927), Post War (1928–1945), Boomers (1946–1964), Gen X (1965–1980), Millennials (1981–1996), Gen Z (1997–2012), Gen Alpha (2013–present). Borders vary slightly by researcher.

Why do generation labels differ between sources?

Generations are social constructs with approximate cutoffs. Marketing and sociology sources may shift start/end years by a year or two at boundaries.

What is Generation Alpha?

Generation Alpha includes people born from about 2013 onward — the first cohort growing up with tablets, voice assistants, and AI-native schooling from early childhood.

Is this the same as zodiac or Chinese zodiac?

No. Generations are demographic cohorts by birth year. Star signs and Chinese zodiac are on the Birthday Calculator.

What generation am I?

Generations are named cohorts born within approximate year ranges, shaped by shared historical events, technology, and culture. Entering your birth year maps you to a label used in marketing, sociology, and everyday conversation — from Baby Boomers to Generation Alpha.

Defined generations

Generation	Year born (approx.)
WWII Generation	1901–1927
Post War / Silent Generation	1928–1945
Baby Boomers	1946–1964
Generation X	1965–1980
Millennials (Gen Y)	1981–1996
Generation Z	1997–2012
Generation Alpha	2013–present

Ranges follow widely cited demographic research; borders between adjacent generations are approximate and vary by source.

Why generations matter

Each cohort experienced different economic conditions, wars, media, and technology. Understanding generational context can help explain values, workplace preferences, and how groups experienced major events — though individuals always vary within a label.

Your place in history

Knowing your generation is a starting point for conversations across age groups — parents and children, teachers and students, or colleagues with decades between them. Pair this tool with the Age Difference Calculator when comparing specific people rather than cohorts.

Examples and use cases

Worked example

Birth year 1990 maps to Millennials (Generation Y) — typically born 1981–1996 — shaped by the rise of the internet, mobile phones, and the 2008 financial crisis during early careers.

Real-world use cases

Workplace training: An HR team tailors onboarding materials after learning most new hires are Gen Z while managers are Gen X.
Marketing persona: A brand checks whether its target audience falls in Millennials or Gen Z before choosing social platforms and tone.
Family history: A grandparent born in 1948 identifies as a Baby Boomer and uses the overview to discuss shared cultural references with grandchildren.
