No a reference to 4/28/2001 is correct. My chart says the week of 4/28/2001.... BTW if someone had a posting here would you have think someone would have posted the details.
April 28, 2001 was a Saturday. As was May 5, 2001. Chart weeks end on Saturdays, not begin. So it either has to be 'the week ENDING 4/28/2001', or 'the week OF April 29, 2001, which would be the week ENDING May 5, 2001.
