The birthday problem can be generalized as follows: Given n random integers drawn from a discrete uniform distribution with range [1,d], what is the probability p(n; d) that at least two numbers are the same? (d = 365 gives the usual birthday problem.) [17] The generic results can be derived using the same arguments given above.
Between 1973 and 1999, September 16 was the most common birthday in the United States, and December 25 was the least common birthday (other than February 29 because of leap years). [12] In 2011, October 5 and 6 were reported as the most frequently occurring birthdays.
June 17, June 18; July 14, July 16; August 14, August 15, August 17; Cheryl then tells Albert and Bernard separately the month and the day of her birthday respectively. Albert: I don't know when Cheryl's birthday is, but I know that Bernard doesn't know too. Bernard: At first I don't know when Cheryl's birthday is, but I know now.
Some say it started in ancient Roman times when flowers were often gifted as a way to celebrate birthdays. Others attribute the custom to the Victorian era when flowers were often given meaning ...
17 is a Leyland number [3] and Leyland prime, [4] using 2 & 3 (2 3 + 3 2) and using 4 and 5, [5] [6] using 3 & 4 (3 4 - 4 3). 17 is a Fermat prime. 17 is one of six lucky numbers of Euler. [7] Since seventeen is a Fermat prime, regular heptadecagons can be constructed with a compass and unmarked ruler.

A birthday attack is a bruteforce collision attack that exploits the mathematics behind the birthday problem in probability theory. This attack can be used to abuse communication between two or more parties. The attack depends on the higher likelihood of collisions found between random attack attempts and a fixed degree of permutations ...
