World Timeline

The following is a list of events as they take place in the world of One Piece, starting from the past and heading toward the present storyline.
Note, however, that aside from the dates of "402", "1120", "1122", and "1127", all dates on this page are either estimates or non-precise time units and therefore are subject to change as the story progresses on.

===Age of the Sea Circle===
This calendar was used by Mont Blanc Noland in his logbook around 400 years ago, dated the year 1120.

Based on exact dates given by Noland, the month-day division in this calendar appears to match the .
===Age of Heaven===
This is the calendar that was used when Nico Robin pretended to recite the history of Arabasta from the Poneglyph in the Tomb of the Kings. In reality, the Poneglyph held information on Pluton. Due to the circumstances, it is unclear whether the information she provided was accurate. It is unknown how months and days were divided in this calendar, and it cannot be matched with the world timeline as no point of reference was given.
