Question 1042724
I will interpret your problem this way:  That the event has happened to you at a particular date this year, and then happens again to you exactly on the same date next year.  By then, approximately 365 days have passed since the occurrence of the same event.  At any day, the probability of the event happening is 1/500, hence the probability of it not happening at any day is 499/500.  The re-occurrence of the event a year hence then follows the geometric distribution.  The probability is given by

{{{(499/500)^364*(1/500)^1 = 0.000965}}},

to three significant figures.

Meaning, there is 0.0965% chance of the same event happening a year hence.  This, indeed, is surprising, and a strange coincidence, if it happens.
