Surely you mean there is a 0.002739726027397 chance that any day is World Statstics Day.
Except on leap years. I think if you check World XYZ days aren’t usually Christmas Day or New Years Day (or probably Thanksgiving). Further for most “professional” XYZ’s they will avoid weekends. So your estimate is flawed…
…and just when you think you know the probability you discover it is non an annual event, but only once every five yrs!
