The period of time understood as “The Present Era” in the Timeline of the Suocéverse is the one that covers the last ~3700 yr of history of the Pokémon World, up to the events in the same timeframe shown in the mainline games (GenⅠ-GenⅧ), and from there up to an uncertain time into the future (as of last edit of this document, GenⅨ). It is also the period of time by which modern in-universe calendars work.
It is preceded by the Previous Era and followed up by THE FUTURE!
It is unknown/undetermined what event provides the calendar Epoch in this era.
The Present Era uses a different epoch than the timeline we see in the games and anime, and “stretches” events of the recent past to help give the modern Pokémon world a more Zeerust-like or Retrofuturism feel, as well as to avoid a too strong coupling to IRL Earth History. For example, events of around two centuries ago such as the burning of the Brass Tower, are pushed back to three centuries. The special case of the confrontations of the Warring Triad has their two historical encounters being pushed back around 600 years each.
Suocéverse timeline considers the events depicted in the remakes of various games (HG/SS, OR/AS, etc) to be refinements, remasters or extensions of the original events, and where there is no conflict they are assumed to take place within the same timeframe.
