Lazers Time category system

Sooooo I figured out a means of telling dates, using the same system as Star Wars

Seeing as the Great War is the one thing that has been canonically confirmed to happen in a certain time(80 years), we can use that as well as other major events to construct a timeline

as i see it, there are 3 main events that have happened, the Great War, Faunus Revolution(the middle of the time scale), and the Battle of Beacon

So we can have 4 different portions of time

BGW(Before Great War)-anything that is seen as not really explained, such as the creations of kingdoms, the beginning of the world, etc.

PGW/FR(Post Great War/Faunus Revolution)-anything past the point of the Great War and Faunus Revolution, combined due to the fact they happen in close proximity(according to lore)

PBoB(Pre-Battle of Beacon) Anything that is seen in the show, up to S3 EP9, where the battle officially began.

PBoB/TS(Post-Battle of Beacon/Time Skip)Anything seen and/or that happened in the 9 month period between S3 and S4, Going from the immediate aftermath of the Battle of Beacon, up to the near future that will be seen in S5
