1/365 I'd think. There are 365 days in a year and it has to match exactly one day. You might be interested in the Birthday Paradox though http://betterexplained.com/articles/understanding-the-birthd...

Birthdays are not uniformly distributed. http://www.panix.com/~murphy/bday.html

Yes, but the probability that it found the same month and day as iLoch's, depend on the uniformity and independence of the month/day generator, not the distribution of actual birthdays.

Yeah my guess was based on the birthday paradox. Though now I see that yes the software probably chose a random number between 1 and 365 so the birthday paradox wouldn't apply.
