    I’m going to assume that your question is just badly worded, as the chance of you being born on your own birthday are obviously 100% for any live birth.

    The chance of anyone being born on your birthday are 1 in 365, or if you’re born on February 29th it’s 1 in 1461.My mum hit the jackpot with that as my brother was born on her birthday, 10th January.I then met and married one of a pair of identical twins born on 10th January.

    the probability of being born on a specific day of the year (your birthday) is 1/365.25 the .25 calculates the extra day added for a leap year.

    Um, there's no probability. Whatever day you're born on is the day that's your birthday. Like wtf. Lol.

    In the strict definition of birthday, that's the day used to celebrate the anniversary of your birth.

    So your 1st birthday is 1 year after you were born. Your 2nd birthday is 2 years after you were born, etc.

    So NOBODY is born on their birthday. They are only born on their birthdate and then celebrate birthdays every year after that.

    100% what other day would a person be born on? That's why they call it your birthday.

    birth day or birth date?

    birth day, eg, day of the week, 1/7

    birth date, eg, day of the year, 1/365.25

    actual birth date, including year,  1 / (365•38)

    (average age in US is 38)

    your birthday comes up once every 365days or 366 every 4th year so on average the chances of you being born on your birthday is 1/365.25 which is aprox 0.27% chance

    100%  Your birthday is determined by the day you were born, so you are always born on your birthday.
