Are you looking for empirical numbers or for a statistical estimate? I
can supply the latter but not the former.

Well, if all possible I would like to know the exact amount of at
least the amount of people born on the same exact date and year in the
U.S. If you were to come up with a statistical estimate, I'd like to
know how you would come up with it.

I dated a girl for about a year that was born 25 hours after me. Can't
say that I've ever heard of anyone else that is, or has ever been, in
a similar situation. Also, I've never been so comfortable with someone
as I was with her. It's funny how these technicalities of chance can
produce such an effect.

Although not exactly on target, my parents were born on the same day,
September 12, exactly on year apart.

Statistically, you could make some assumptions to give you a basic
answer.  The odds of a partner having the same exact birthday would be
around 1/366.  If you assume that couples are typically within 7 years
of each other's age (just a guess), then the odds of your partner
being born in the same year as you is around 1/13. A very simple
calculation would then tell you that the odds of both events (same
day, same year) would be 1/4758. You could then get the number of
married couples from the census bureau or similar organization and
divide the number of couples by 4758.

Bit if an aside- I've never really been one to go in for starsigns and
stuff, but a friend of mine recently pointed out that out of a group
of about 45 friends on holiday together, all but about 3 had the same
6 or 7 starsigns- and most of those were born in the spring/summer.
This may be a bit of a coincidence, but i do find that most of the
people i get on well with have birthdays in the spring and summer.
Also, as a 'summer baby' myself, most of my boyfriends have had
birthdays in Spring, particularly April.

This is a good question.

it can be possible that the all couples are from the exact date and exact year too.

So one can not say exactly that there will be some thing as 1 in 1000
or 1 in 100 of them.

But science has surveyed in many countries and found that the
probalility of happening of such things are 15 in a life time.

Hope this is ur answers.

I belong to one of these rare couples.  My partner and I have known
each other since we were 12 years old and we are now 47.  We were both
born on the exact day and year, August 26, 1957, only I was born at
12:01pm and he was born at 3:25pm.  We were born in NC only an hour
away from each other.  We went to Jr. High and High School together
and met up again at our 20th High School reunion in 1995.  He emailed
me last May, insisted on driving from NC to IN to take me out for
dinner and the rest is history.  We are like mirror images to each
other.  We share the same sense of humor, love for the same music and
can predict what the other is thinking just my looking into our eyes. 
We have compared our lives over and over and it is still quite amazing
how parallel they have been.  We both have lived on the cutting edge
most of our lives as Virgos love drama, extreme knowledge
(philosophical) and excitement.  The strangest thing is when we
comprend in the exact same way, where something happens, and we both
either reach for, go for, or say the exact same thing in response to
the given situation.  We have all done this at times but not ALL the
time!  It is fun to see where our differences are since there are so
few.
