90

The year 90 (XC) was a common year beginning on a Friday of the Julian calendar, in force on that date.

In the Roman Empire, it was known as the Year of the Consulate of Augustus and Nerva (or less frequently, year 843 Ab urbe condita). The designation 90 for this year has been used since the early medieval period, when the Anno Domini became the prevalent European method of naming years.
