If a person were born on Feb. 29 would their b-day just be counted as Jan. 1 or would they have to wait 4years

Actually, the easiest way to look at it is that the person was born on the day after February 28.  So, it does not matter if it's leap year or not, the person celebrates another year of life on the day after Feb. 28 whether it's Feb 29 or March 1.\nNow, if the person is a woman who stops counting years after the age of 29, then it's probably easier to only county your birthday every 4 years ;-)

If you have a birth certificate that states another birthdate, yes. Otherwise, no.

They couldn't have been born on Feb 29, 1991. It wasn't a leap year

Its the fourth Thursday in the month of November.  The number date changes every year.  This year its the 23rd.  It falls on that day every 7 years.  I know this because its my sons bday and he was not born on Thanksgiving.  He was born 3 days before back in 1980

You have an error in your first statement which means the logic after that is flawed.\n\nThere aren't 52 weeks in a year, there are 52 weeks and 1 day. That's why your birthday will be on a Tuesday (say) this year and on a Wednesday the year after (discounting leap years).

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.

You could come with a formula but it would be complex. \nThis year Jan 1 was on Sunday. Next year it will be on Monday. Every year, it gets a day later, except when there is a leap year, then the next year it's two days later. Because leap year happens every 4 years and there are 7 days in the week, the pattern takes 28 to repeat. January 1 will come on Sunday 7 times in 28 years, but the years it happens won't be evenly spaced.\n\nAs one answerer said above, you get a Friday the 13th when the month start on a Sunday. So you get a Friday the 13th in January 7 times every 28 years.\nIt works the same for all the other months -- 7 Friday the 13ths over the course of 28 years, but not evenly spaced.\n\nTo make a formula, it would have to include a method that computed where you are in the 28 yr cycle, whether it's a leap year or not, etc.\n\nNote: Since February has an even 4 weeks in non-leap years, if February has a Friday the 13th in a non-leap year, March will have one, too.

Lots of different ways.  There just needs to be an established convention.  And you need to make sure that no confusion can arise.\n\nYou can write it in a YYYYMMDD format, so today would be 20061107.\n\nYou can also express it in number of days since a certain date.  For example, you could make January 1, year 1 A.D. equal Day 1 and count from there.

OCTOBER 4 is the most common birthdate.  \nthe second most common birthdate, (in the USA at least) is November 15.\n\n(not coincidentally Oct 4 is 9 months after new-year's eve, and Nov 15 is 9 months after Valentines day)

I think you'd have to use a different birth year. If the age  limit or whatever is 18 and older, figure out what year you'd have to be born in to be 18 today. You would also have to use any date before today as your birthday.

Well the least common is clearly Leap Day (February 29th) because it only comes once every four years.\n\n The most common birthday would be negligable in many cases for a few reasons. First, in the U.S. the highest birth month is September. In England its July. It varies wildly by culture, and by time. A mere 10 years ago, the most common birth month in England was March. SO, if you're talking about the U.S. then in any given year (as long as it remains September, which it has for a few years) there is a one in thirty chance of any day in September being the most common birthday of that particular year.

well technically no one has a birthday that day yet, some of you may celebrate the ANNIVERSARY of your birthday that day, but no one has been born on it yet.

1. It takes a year longer to finish school and start your career.\n2. If you're going back to school after, your skills might be rusty.\n\n_____________\nmmikulenka: I think you're confusing gap year and leap year.  A person born during a leap year can be born on Feb. 29th, and only have an actual birthday every four years (I actually know someone who was born on Feb. 29th).  A gap year is a year of either between high school and university or after university before starting a career.  All the days are still there.

Your birthdate does not go to the IRS.  Your accountant or the person filing your taxes would be the only person that views that information.  The birthdates are used in determining child tax credits etc.

I have not found a computation site that computes a date\ngiven number of days.  So...   \n I would compute the total number of days old I am and count back on the Christian calendar. Here is a starter.\n 2006    May 12\n 2005    365   days \n 2004    730   days  added 365 to previous total\n 2003   1096   days  added 366 to previous total(leap year)\n 2002   1461   days  added 365\n etc.  Leap years are evenly divisible by 4 and the leap\nday is Feb. 29. Normally February only has 28 days.\n When you reach a number of days that is greater\nthan your age of days, then count forward on the Christian\ncalendar while counting down on the days. When you reach\nthe days of your age you will have the date.\n  I'm sure there's an easier way but until you find it,\nthis is the best I can do.
