The last MM2 leaderboard I found evidence for appears to have lasted about 11.5 days for the 2025 Halloween event, based on a post from MM2 Overview.

What that means

  • A community source specifically says, “The 2025 Halloween Leaderboard is 11 1/2 days long!”
  • Another discussion says MM2 leaderboards usually run for “a couple weeks” during holiday events, which lines up with that estimate.

Small caveat

There isn’t a single official duration shown in the sources I found, so this is best treated as the most recent public estimate rather than a hard rule.

Quick Scoop: the last MM2 leaderboard seems to have been around 11.5 days long.
