There's an intentional continuity flaw in The Sopranos.
I forget exactly the year when it happened, probably between seasons 3 and 4 because it had the largest gap, but they skipped a year. I could have told you the exact references at the time, now I forget. But at the end of season three it's clear it's spring 2001, then in season four, only three months later in the show in plot time, it's fall 2002.
I guess it's not a 'goof', they did it so they can make current references. Or maybe they did it so they wouldn't have to talk about the events of 9/11 as if they were currently happening when Meadow was in New York.
