The Iranian calendars or Iranian chronology are a succession of calendars invented or used for over two millennia in Iran, also known as Persia. One of the longest chronological records in human history, the Iranian calendar has been modified time and again during its history to suit administrative, climatic, and religious purposes. The most influential face in laying the frameworks for the calendar and its precision was the 11 century Persian polymath, hakim Omar Khayyam. The modern Iranian calendar is currently the official calendar in Iran. It begins at the midnight nearest to the instant of the vernal equinox as determined by astronomic calculations for the Iran Standard Time meridian. It is, therefore, an observation-based calendar, unlike the Gregorian, which is rule-based.
A calendar era is the period of time elapsed since one epoch of a calendar and, if it exists, before the next one. For example, it is the year 2021 as per the Gregorian calendar, which numbers its years in the Western Christian era.

Persis, better known in English as Persia, or Persia proper, is the Fars region located to the southwest of modern Iran, now a province. The Persians are thought to have initially migrated either from Central Asia or, more probably, from the north through the Caucasus. They would then have migrated to the current region of Persis in the early 1st millennium BC. The country name Persia was derived directly from the Old Persian Parsa.
Hydarnes I or Hidarnes I, also known as Hidarnes the Old by contrast with his son Hidarnes the Young, son of Bagābigna, was a Persian nobleman of the Orontid dynasty during the Achaemenid Empire in the late 6th and early 5th centuries BC. He was one of the seven conspirators against the usurper, Gaumâta, who killed him and then proclaimed Darius I as the Persian king. His name appears in the Behistun inscription among the six conspirators who supported the rise of Darius the Great. Hydarnes then served Darius I as a commander and remained influential during his reign.
Gobryas was a common name of several Persian noblemen.
The Achaemenid Empire, also called the First Persian Empire, was an ancient Iranian empire that was based in Western Asia and founded by Cyrus the Great. It reached its greatest extent under Xerxes I, who conquered most of northern and central ancient Greece, including the city of Athens, in 480 BC. At its greatest territorial extent, the Achaemenid Empire stretched from the Balkans and Eastern Europe in the west to the Indus Valley in the east. The empire was larger than any previous empire in history, spanning a total of 5.5 million square kilometers.
