Fun birthday facts
The day of the week you were born is calculated with the same math calendar apps use — no guessing, so you can settle family debates about whether Grandma really was born on a Sunday. Your Western zodiac comes from the date ranges astrologers have used for centuries, and your Chinese zodiac follows the 12-year animal cycle (Rat, Ox, Tiger, Rabbit, Dragon, Snake, Horse, Goat, Monkey, Rooster, Dog, Pig). Generation labels are the common ones: Gen Alpha (2013+), Gen Z (1997–2012), Millennial (1981–1996), Gen X (1965–1980), Baby Boomer (1946–1964), Silent Generation (1928–1945), and Greatest Generation (1901–1927). Everything runs in your browser, so your birthdate never leaves your device.

Frequently asked questions
Is my birthdate stored or sent anywhere?
No. The birthday lookup runs entirely in your browser — your birthdate never leaves your device and nothing is stored or tracked.
How is the days-lived count calculated?
It is an exact calendar-day count from your birthdate to today, correctly accounting for leap years.
My Chinese zodiac animal looks wrong — why?
The Chinese New Year falls in late January or early February, so if you were born in January or early February your animal may be the previous year's.
Which generation do I belong to?
Gen Alpha (2013+), Gen Z (1997–2012), Millennial (1981–1996), Gen X (1965–1980), Baby Boomer (1946–1964), Silent Generation (1928–1945), or Greatest Generation (1901–1927).
