What if you were born in a leap year, on Feb. 29th?

They record it by the actual birthdate.  02/29/XXXX.  The fact that someone's birthdate only occures each 4 chronological years does not negate the fact that they are 4 years older.  Did you think that the government changed your age to one day off of your birthdate on years that included the 29th of February?  They don't.

They probably have to pick the 28th to be their birthday every year, and REALLY celebrate when it's a Leap Year.(and they can lie and tell the truth about their age at the same time...ex. a 20-yr-old can say they just celebrated their 4th birthday!)

No.  Nobody has ever been born on that day.  It cannot be explained.  It is a freak of nature.  If your parents told you that was your birthday, then you were adopted.  That is the day that all adoption agencies use for the kids.

Nov. 4th here!  I think your birthday IS November 4th, not "was".  See, not "bi#$y, just logical and straighforward!

There's a mistake in your question.  But I'm going to write this assuming your question is correct.  See the very end of my answer for an important point.\n\nWhether you're "special" depends on your definition of special, I guess.  It does put you in a fairly rare class of dates.\n\nLet's look at the likelihood of having a birthdate that matches your conditions.\n\n1) The year of your birth is a prime number.\n2) The month of your birth is a prime number.\n3) The day-of-the-month of your birth is a prime number.\n\nIn the past 100 years, there were only 13 years that were prime:  1907, 1913, 1931, 1933, 1949, 1951, 1973, 1979, 1987, 1993, 1997, 1999, and 2003.\n\nIn any given year, there are only five months that are prime:  2, 3, 5, 7, and 11.\n\nAnd in a given month, there are only eleven possible days that are prime, though not all of these occur in every month:  2, 3, 5, 7, 11, 13, 17, 19, 23, 29, and 31.\n\nLet's calculate how many total days there were in the past 100 years, and how many of those dates meet your criteria.\n\nFirst, we'll calculate the total number of days in the past 100 years, ignoring leap years (we'll add those in later).  Every year has 365 days, so 365 times 100 equals 36,500.\n\nNow, let's add in the leap years.  Leap years come every 4 years, except that if a year is divisible by 100, it's not a leap year.  Except if it's divisble by 400, it is a leap year.  The only "exceptional" year in the past 100 years is the year 2000, and that's divisible by 400, so it was a leap year.  So there were twenty-five leap years over the past 100 years (the period from April 22, 1906 through April 21, 2006).\n\nSo the total number of days in the past 100 years is 36,525.\n\nNow, how many of those dates fit your criteria?\n\nIn a non-leap year, there are 52 dates that fit your criteria.  All leap years are divisible by four, and thus they are not prime numbers, so we can completely ignore leap years in this calculation.  The dates are:\n\nFebruary 2, 3, 5, 7, 9, 11, 13, 17, 19, 23\nMarch 2, 3, 5, 7, 9, 11, 13, 17, 19, 23, 29, 31\nMay 2, 3, 5, 7, 9, 11, 13, 17, 19, 23, 29, 31\nJuly 2, 3, 5, 7, 9, 11, 13, 17, 19, 23, 29, 31\nNovember 2, 3, 5, 7, 9, 11, 13, 17, 19, 23, 29\n\nAdd them up, and you'll see there are 52 of them.  52 dates per year, multiplied by thirteen years that are prime comes out to 676.\n\nSo out of 36,525 dates someone might have been born in the past 100 years, only 676 of them meet your criteria.  That's about 1.85% of them.\n\nSo, if we assume that the odds of being born on any given date is about equal (not true) and that a given person is a random age between 0 and 100 (also not true), they have about a 1.85% chance of meeting your criteria.\n\nHOWEVER, and here we get to the mistake in your question, you were not born on a date with all prime numbers.  1957 is not a prime number; its factors are 19 and 103 (19 * 103 = 1957).\n\nSo it turns out you're not special at all.  You're just normal, like the rest of us.  :)

Yes; there are potentially several reasons why a person wouldn't know his or her real date of birth. In some countries, governments don't keep very complete records. Children are orphaned all over the world, of course, and might not have any adults around who remember when the children were born.\n\nThere is, of course, a weird phenomenon that occurs when someone is born on February 29th. Although s/he knows the date of birth, the way that one measures age is complicated, since s/he only has a birthday in leap years.  In Korea, people count age differently than we do in the West. When someone is born, we think of him or her as zero, while the Koreans would say one. When the year changes, one adds another year, instead of adding a year on the birthday. So, everyone in Korea is actually a year or two younger (in Western terms) than they say they are.\n\nBut, back to your original question: I think that it is possible to have a judge declare a date of birth that one could use for any legal reason whatsoever.

no, it goes by the day you were born. good question though.

INTERESTING HOW YOU JUST HAPPEN TO ASK THAT SPECIFIC DATE :)\n\nYOUR ON TO SOMETHING.  STAY ON IT. YOUR ON THE RIGHT TRACK.\n\nNOBODY KNOWS. THATS BIBLICAL.  THE BIBLE SAYS: THE HOUR OR DAY.  IT DOESN'T SAY THE YEAR CAN NOT BE KNOWN.!\n\nNobody can know the year. very simple reason. NOBODY know's if Jesus was born on a Leap Year.\n\nYou are into the number crunch or know someone who is.\n\nIt could be 2007 or 2012. you can't know yet. If we go through 2007, then Jesus WAS born on a leap year. :)  Keep your eyes on 2012.\n\ngreat question.  have a good week.

No, because regardless of the date, you are still technically another year older by the time march 1st comes around, regardless of the date.\n\nAlso, you can celebrate your birthday anytime you want.  For example, scholars have deduced that jesus wasn't born on dec 25, but we celebrate it then anyways.

Every 4 years is a leap year.  2008, 2012, 2016 etc.

no\nYour birthday is the day after.  Midnight officially belongs to the next day.\n\nAlthough it'd be cool to celebrate it that way.

20 turning 21. If someone was born on feb 29 1985, well they will be living in a different universe from us because 1985 is not a leap year.

congrats, but that is such a weird date to be born on... i've heard that there is no significance to those numbers, but still... a little weird.
