Timeline of Warcraft

I was reading in the WoW Wiki and got dragged into the timeline rabbithole. So the major event that distinguishes the major events is BDP and ADP, Before Dark Portal and After Dark Portal. To give you the basic rundown: The formation of Azeroth is some 100,000 BDP, 0 ADP is the events of Warcraft 1, Battle of Mount Hyjal and events of Warcraft 3 conclude at 21 ADP, W3 TFT happen in 22 ADP, and WoW begins at 25 ADP but here's the fucking crazy part. TBC happens throughout 26 ADP, WOTLK happens throughout 27 ADP, Cataclysm 28-30 ADP, MoP WoD Legion 30-32 ADP, BFA Shadowlands 33-36 ADP, Dragonflight 40 ADP and TWW 41+ ADP.

I don't know if it's out perception of time in game but these patches took YEARS but in lore time was only a matter of 15 years... Like that is the craziest thing to me. In my mind atleast the lore in game is the same as irl time.
