That would depend on the life expectancy. In America the average life expectancy is 78 years old which would mean:  78 birthdays.

That is if it is his birthday, if it is his family then it would have to be....how many family members he knows and how many birthdays that they have had. If this is his friends birthdays, then it would have to depend on how many friends he has and how many birthdays that they have had. Easy, really. Unless I got this test wrong? Seems easy to me.
