A birthday is the day you were born. Was every single person born on exactly the same day? Of course not.
All are born on different days.
They all have different birthdays. Way to assume they were all born on the same day.
all I can tell you about birthdays is Mr.Squiggles, his is January 31 2009
Impossible to say. Not all publish birthdays.

Let us assume that there are exactly 365 days in a year and that birthdays are uniformly randomly distributed across those days. First, what is the probability that 2 randomly selected people have different birthdays? The second person's birthday can be any day except the first person's, so the probability is 364/365. What is the probability that 3 people will all have different birthdays? We already know that there is a 364/365 chance that the first two will have different birthdays. The third person must have a birthday that is different from the first two: the probability of this happening is 363/365. We need to multiply the probabilities since the events are independent; the answer for 3 people is thus 364/365 × 363/365. You should now be able to solve it for 4 people.

There is no specific collective noun for birthdays, however a noun suitable for the situation can be used; for example a cluster of birthdays, a series of birthdays, or a respectable century of birthdays.
