Oh, isn't that a fun thought! It's like finding a happy little coincidence in the world. There may be a few people who share your name and birthday, but remember, each one of us is unique and special in our own way. Just like every tree in the forest has its own beauty, you bring something special to the world that only you can offer.

BeauI found a lady, born on the same day, same year as myself. We met in church... we have the same dress sense and always make similar choices. We also bear the same name GLORIA and our initials are GIO..
The likelihood of someone sharing both your name and birthday depends on various factors such as the popularity of your name and the total population. According to the birthday paradox, in a group of just 23 people, there is a greater than 50% chance that two people will share the same birthday. However, finding someone with both your exact name and birthday would be much rarer and would require specific data on name frequencies and birth dates.
Well, unless you're a real-life superhero with a superhuman ability to keep track of every single person in the world who shares your name and birthday, I'd say it's pretty impossible to give you an exact number. But hey, who knows, maybe there's a secret society of people out there with your name and birthday planning a surprise party just for you.
The first thing to note is that names and birthdays are independent of each other. Someone born on 5th June isn't more likely to be called Chris, and someone called Katie isn't more likely to be born on 20th October, or whatever.
Thus the probability is equal to the probability someone has your name, multiplied by the probability someone has your birthday.
The latter is just 1/365.25, as you are equally likely to be born on each day.
The former could be anything. If you have a really common name, that 1 in 1,000 people have, then the probability of someone having the same birthday and name as you will be 1/365,250
Multiply this probability by the world population (which we'll round to 7 billion) and you get:
7,000,000,000/365,250
= 19,165
so 19,165 people would have the same name and birthday as you!

How many people have a birthday on the same day?
The answer is 9 000 000 people
How many people have the same birthday as you?
If there are 300,000,000 people in the US, then on average you share your birthday with over 82,000 people. Of course, if your birthday is 2/29, you would share it with about 1/4th of that number.
How many people have the same birthday in the US?
EVERYBODY in the US has the same birthday as someone else in the US. The converse would be that someone in the US has his/her own birthday and nobody else in the entire population of 300,000,000 people in the US was born on that day.
How many people are needed in a room before two of them share the same birthday?
For the chance to be at least 50% that two people share the same birthday, there needs to be 22 people. For the chance to be exactly 100% that two people share the same birthday, there needs to be 366 people. If there was 365 people, there would be a very small chance that each person in the room would have different birthdays. With 366 people, there are not enough individual days for every person to have a different birthday, so there has to be at least one pair.
How many people have the same birthday in the world?
It must be about 360,000 - the approximate number of world births per dayit is estematet to be that 150 million or billion(i cant remember) people share your birthday
