Why is September the Most Popular Month for Birthdays?
Now you might be thinking what’s so special about September that makes it the most popular month for birthdays. From personal experience, I can say that September is a good time for baby making. There are a few reasons actually.
- The most popular reason for September being the most popular month for birthdays is Christmas and new year. Because most people spend time with their families, boyfriends, girlfriends or friends during these holidays. And the best part is that you get a lot of days off from work or school. So people tend to use these holidays for giving birth or getting pregnant.
- Another popular reason is that the weather is perfect for giving birth in September. It’s not too hot and not too cold. And also, most of the hospitals don’t have a lot of patients in September. So it’s the perfect time to give birth.
- September is also a popular month for weddings. This means that many women who get married in September are more likely to have their babies in September.
- Another reason September is a popular birthday month is that it starts the school year. Many parents who want their children to be born before the school year starts are likelier to have their babies in September.
Now let’s find out if you share your birthday with famous people. I looked up some of the most popular birthdays and here are some famous people who share your birthday.

What Are the Least Common Birthday Dates?
I know everyone cannot have their birthday on the same day; some days are more popular than others. So I decided to find out which days are the least popular for birthdays.
The least common birthday is December 25th. This is because it’s a leap year and not everyone is born on a leap year. And also, Christmas is a very busy time for most people who don’t have time to celebrate their birthday.
Least Popular Birthdays Month
- December 25th
- January 1st
- December 24th
- July 4th
- January 2nd
- December 26th
- November 27th
- November 23rd
- November 25th
- October 31st
It’s strange because the holidays are the most popular time for birthdays. Yet, the least popular days are also holidays. I guess people just don’t want to share their birthday with everyone celebrating a holiday. But whatever the reason, these are the least popular days for birthdays.
How Common Is Your Birthday? (Interactive Heat Map)
The data and statistics I shared in this article are interesting, but what if you want to know how popular your birthday is? Well, I have created an interactive heat map showing different birthdays’ popularity. Just click on the dots and it will show you how many people have the same birthday as you.
How to Calculate the Popularity of Your Birthday?
To calculate the popularity of your birthday, you’ll need to know two things.
- The number of births in the United States in the year you were born
- The total number of days in that year.
You can find both of these pieces of information on the U.S. Census Bureau’s website.
Once you have those numbers, simply divide the number of births by the number of days in the year. The resulting number will be a decimal between 0 and 1. To convert it into a percentage, multiply by 100. The resulting number will tell you what percentage of people in the United States were born on the same day.
So, for example, if you were born on January 1st, 1980, there were 3,762,000 births in the United States that year (according to the U.S. Census Bureau). There are 365 days in a standard year, so if we do the math (3762000/365), we get 10309.59 or about 10%. So about 10% of people in the United States were also born on January 1st.

I know that many people are interested in the number of births in the United States. So I have created a graph that shows the number of births from 1990 to 2020.
As you can see, the number of births has increased over time. This is because the population of the United States has been increasing. And also, more women are having babies at an older age.
