LOL...No they haven't. Easter always occurs on a Sunday, Pesach always begins on the 15th of Nisam. Since this is not an issue of different interpretations it is incredibly easy to prove you wrong on this. With the exception of 2010 they have fallen on different days, sometimes separated by as much as 4 weeks (2005 & 2008).
Prior to the year 2000 how many times have
they occurred in the same week ?
When you are in a hole the smart thing to do is to stop digging. If, by the same week you mean Easter +/- 7 days the number is really very high. If your point of reference is Easter being the beginning of a week the number is still significant and certainly greater than 0/2000. If you care to actually check it out instead of repeating the lunacy (no pun intended) you have heard you can check it out for every year past and future at the following website:
