[Primaries in bold]
States that are split vertically had different dates for different party contests. The shade to the left of that line corresponds with the month in which the Democratic contest took place and the right side represents the Republican contest.

A few notes:
1) For a year when both parties had "contested" nomination races, there really was a surprising dearth of frontloading. California and Ohio inched up to join Super Tuesday, but those were really the only moves of significance. Even the GOP's allowing for February contests didn't serve as that big a departure from the 1996 calendar.
2) Having said that, Arizona, Delaware, Michigan and Virginia all took advantage of those new rules by holding February contests. It was those contests that kept the Bush-McCain race in the news while the Democrats waited out the period between New Hampshire on February 1 and Super Tuesday a month later. Bill Bradley sincerely wishes the DNC had let some of those other states go that wanted to go earlier. Then again, that was part of the reason that the Democratic side had a "contest" for its nomination. I keep saying "contest" simply because Bush-Gore was a done deal to the point that political scientists were making bets about the race in early 1999. And no, it wasn't your truly, who was merely a baby political scientist at the University of North Carolina at the time.
3) The February allowance by the GOP opened the door for a transitional 2004 calendar and then a 2008 calendar where February was the new March: where most states had taken up residence. So while frontloading between 1996 and 2000 was lacking, the rules changes for 2000 set the stage for the calendars that would develop for the races throughout the rest of the decade.
