Year 106 (CVI) was a common year starting on Thursday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Commodus and Civica (or, less frequently, year 859 Ab urbe condita). The denomination 106 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

One million (1,000,000) or one thousand thousand is the natural number following 999,999 and preceding 1,000,001. The word is derived from the early Italian millione (milione in modern Italian), from mille, "thousand", plus the augmentative suffix -one. It is commonly abbreviated as m or M; further MM ("thousand thousands", from Latin "Mille"; not to be confused with the Roman numeral MM = 2,000), mm, or mn in financial contexts.
