With nearly infinite worlds, each with their own rotation and orbital periods, tracking time can be extremely complicated.

Pact Standard Time, sometimes simply called Pact Standard, is a universal system of measuring time based on the unusually identical rotational periods of Castrovel and Triaxus, which themselves correspond to the shift schedule on Absalom Station; and Absalom Station’s orbital period. 

Both Castrovel and Triaxus have the same rotational period, corresponding to 1 day. These days are divided into 24 hours of 60 minutes each.

Absalom Station’s orbital period takes 365 of these days, divided into 52 weeks of 7 days each, with these weeks grouped into 12 months.

When people want to refer to a particular planet’s rotation or orbit, they generally use terms like “local day” or “local year.” 

Modern history records years in ag, which stands for “After Gap,” referring to the number of years since the end of the Gap in the Pact Worlds system, when memory and history once again became reliable. Events that occurred before the oldest edge of the Gap are often referred to as pg (“Pre-Gap”) and measured in how many years before the Gap they occurred, with a date like 300 pg meaning the event occurred 300 years before the onset of the Gap. On some worlds, however, scholars use the preexisting local calendars for events before the Gap. Those researching the cultures from Golarion, for instance, sometimes uncover documents referring to dates in ar or “Absalom Reckoning,” a measurement believed to have been used for nearly 5 millennia, starting with the ascension of a now-dead and mostly forgotten god of humanity named Aroden. Dating anything within the Gap is always a highly dubious proposition, and those who attempt to make claims about such things usually count forward or backward from the nearest edge, such as “roughly 500 years after the onset of the Gap.”
