Galactic Dating Standard

Not to be confused with the Galactic Dating Service, the Galactic Dating Standard is a dating standard that became popular following the Great Hat Dispute.

PHD
PHD (Post Hat Dispute) refers to events that follow the Great Hat Dispute. It is used to mark events following the conclusion of the Great Hat War.

AHD
AHD refers to events that precede the Great Hat Dispute. The origins of the acronym are shrouded in mystery, and any idea what it may stand for is a matter of debate among scholars.

Consequences
One major consequence of this dating standard is that the exact duration of the Great Hat Dispute is unknown. As such, it is common to date the Dispute as both 0 AHD and 0 PHD.
