The terms anno Domini (AD) and before Christ (BC) are used to label or number years in the Julian and Gregorian calendars. The term anno Domini is Medieval Latin and means "in the year of the Lord", but is often presented using "our Lord" instead of "the Lord", taken from the full original phrase "anno Domini nostri Jesu Christi", which translates to "in the year of our Lord Jesus Christ".
Tribune was the title of various elected officials in ancient Rome. The two most important were the tribunes of the plebs and the military tribunes. For most of Roman history, a college of ten tribunes of the plebs acted as a check on the authority of the senate and the annual magistrates, holding the power of ius intercessionis to intervene on behalf of the plebeians, and veto unfavourable legislation. There were also military tribunes, who commanded portions of the Roman army, subordinate to higher magistrates, such as the consuls and praetors, promagistrates, and their legates. Various officers within the Roman army were also known as tribunes. The title was also used for several other positions and classes in the course of Roman history.

A dynasty is a sequence of rulers from the same family, usually in the context of a feudal or monarchical system, but sometimes also appearing in elective republics. Alternative terms for "dynasty" may include "house", "family" and "clan", among others. The longest-surviving dynasty in the world is the Imperial House of Japan, otherwise known as the Yamato dynasty, whose reign is traditionally dated to 660 BC.
A calendar era is the year numbering system used by a calendar. For example, the Gregorian calendar numbers its years in the Western Christian era. The instant, date, or year from which time is marked is called the epoch of the era. There are many different calendar eras such as Saka Era.

The Seleucid era or Anno Graecorum, sometimes denoted "AG", was a system of numbering years in use by the Seleucid Empire and other countries among the ancient Hellenistic civilizations. It is sometimes referred to as "the dominion of the Seleucidæ," or the Year of Alexander. The era dates from Seleucus I Nicator's re-conquest of Babylon in 312/11 BC after his exile in Ptolemaic Egypt, considered by Seleucus and his court to mark the founding of the Seleucid Empire. According to Jewish tradition, it was during the sixth year of Alexander the Great's reign that they began to make use of this counting. The introduction of the new era is mentioned in one of the Babylonian Chronicles, the Chronicle of the Diadochi.
5 is a number, numeral, and glyph.
Year zero does not exist in the anno Domini system usually used to number years in the Gregorian calendar and in its predecessor, the Julian calendar. In this system, the year 1 BC is followed by AD 1. However, there is a year zero in astronomical year numbering and in ISO 8601:2004 as well as in all Buddhist and Hindu calendars.

The Spartan army stood at the center of the Spartan state, whose citizens trained in the disciplines and honor of a warrior society. Subject to military drill from early manhood, the Spartans became one of the most feared military forces in the Greek world. At the height of Sparta's power – between the 6th and 4th centuries BC – it was commonly accepted by other Greeks that "one Spartan was worth several men of any other state". According to Thucydides, the famous moment of Spartan surrender on the island of Sphacteria, off Pylos, in 425 BC, was highly unexpected. He wrote that "it was the common perception at the time that Spartans would never lay down their weapons for any reason, be it hunger, or danger."
The 20th century of the Common Era began on 1 January 1901 and ended on 31 December 2000, according to the Gregorian calendar.
The proleptic Gregorian calendar is produced by extending the Gregorian calendar backward to dates preceding its official introduction in 1582. In countries that adopted the Gregorian calendar later, dates occurring in the interim are sometimes "Gregorianized" as well. For example, George Washington was born on February 11, 1731, as Great Britain and its possessions were using the Julian calendar with English years starting on March 25 until September 1752. After the switch, that day became February 22, 1732, which is the date commonly given as Washington's birthday.
Strategos or Strategus, plural strategoi, is used in Greek to mean military general. In the Hellenistic world and the Byzantine Empire the term was also used to describe a military governor. In the modern Hellenic Army it is the highest officer rank.
