I happened to notice today that the day on skyblock was (if you do F3) 52562. This seemed like a fairly large time so I did a calculation- a minecraft day is 20 minutes, so day 52562 is 1,051,240 minutes, 17,520.7 hours, and 730.028 days. This means that today is the Skyblock server's 2nd birthday. Happy 2nd birthday, skyblock!
