About the Birthday Report
Birthday Report puts everything about a birthday on one page. Enter a date of birth to see your zodiac sign (and whether you were born on a cusp), your Chinese zodiac animal and element — worked out from the actual Lunar New Year date, so January and February birthdays get the right animal — your birthstone and birth flower, your generation, the weekday you were born, your exact age, your life path number and when your next birthday falls. It also shows how common your birthday is, ranked from 1 to 366 using 21 years of real US birth records from the CDC and the Social Security Administration, and how many babies were born in the US on the very day you were born, for dates from 1994 to 2014.

- 2 Read the zodiac sign, Chinese zodiac, birthstone, flower and generation.

Frequently asked questions
What is the most common birthday?
In the US, 9 September is the most common birthday, closely followed by other mid-September dates such as the 19th, 12th and 17th — about nine months after the end-of-year holidays. The data is the CDC and Social Security Administration count of every US birth from 1994 to 2014.
What is the rarest birthday?
29 February, since it only comes round in leap years. Among the dates every year has, 25 December is the rarest, followed by 1 January, 24 December, 4 July and 2 January: far fewer births are scheduled (inductions and planned caesareans) on holidays.
Why does my Chinese zodiac sign differ from the year I was born?
The Chinese zodiac year starts at Lunar New Year, which falls between 21 January and 20 February, not on 1 January. If you were born in January or early February before that year’s Lunar New Year, your animal is the one for the year before. This report checks the actual Lunar New Year date for your birth year.
What is a zodiac cusp?
A cusp is the day or two when the Sun moves from one sign into the next. The exact day shifts from year to year, so someone born on a cusp date can be either sign depending on their birth year and time. A full birth chart with your time and place of birth settles it.
How are generations defined?
This report uses the Pew Research Center ranges: Silent Generation 1928–1945, Baby Boomers 1946–1964, Generation X 1965–1980, Millennials 1981–1996 and Generation Z 1997–2012. For Generation Alpha (2013–2024) and Generation Beta (2025–2039) it uses the commonly cited ranges, since Pew has not set them. Other sources draw the lines a year or two differently.
Is my date of birth stored?
No. The report is worked out when the page loads and nothing is saved. A report link contains the date, so only share it with people you are happy to tell your birthday.
