About How Rare Is My Birthday
Welcome to HowRareIsMyBirthday.com. The site is built around one main question: how rare is my birthday?
The birthday rarity calculator is the heart of the site. It compares your month and day with the other dates in 85,712,738 recorded U.S. births from 1994–2014, then shows a rarity score, ranking, recorded birth count, and a few useful birthday details.
From there, you can compare the rarest birthdays, see the most common birthdays, find celebrity birthday matches, or try one of the focused birthday calculators.
What you’ll find here
You can use the main calculator for a quick rarity answer, then dig deeper into the ranking pages if you want to see where your date sits among all 366 calendar dates.
The celebrity birthday finder adds a fun comparison by showing famous people born on the same month and day. The calculator collection stays close to that same idea, with milestone tools plus useful date tools for your birthday countdown, exact age, birth weekday, and major birthday ages.
The goal is to keep the site useful, easy to understand, and fun to use. The unicorn artwork gives it personality, while the rarity data and its sources stay easy to find and understand.
Questions, corrections, and ideas
If you spot a strange result, a data issue, a typo, or a calculator that could be clearer, I’d like to hear about it. Suggestions for useful birthday calculators are welcome too.
You can send a message through the contact page. Reader corrections and questions are especially helpful when they make the rarity calculator or its supporting pages easier to understand.
Who built the site?
How Rare Is My Birthday was created by Don St Germain. The idea was to make a birthday rarity calculator that feels more inviting than a plain number on a blank page, while still keeping the result and methodology easy to understand.
The site is intentionally focused: birthday rarity, rare and common birthday rankings, celebrity birthday matches, and useful birthday calculators. That narrower focus should make it easier for visitors to know exactly what the site is for.
The colourful design and unicorns are part of the fun, but the main goal is simple: give visitors a quick answer, explain what it means, and offer a few genuinely related tools if they want to keep exploring.
