52

Year 52 (LII) was a leap year starting on Saturday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Sulla and Otho (or, less frequently, year 805 Ab urbe condita). The denomination 52 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.

Phone numbers in Mexico are made of ten digits with either two-digit area codes (for Mexico City, Monterrey, and Guadalajara and their respective metropolitan areas) or three-digit area codes for the rest of the country.

A vertical service code (VSC) is a special code dialed prior to (or instead of) a telephone number that engages some type of special telephone service or feature. Typically preceded with an asterisk, or * (star), key on the touch tone keypad and colloquially referred to as star codes, most are two digits in length; as more services are developed, those that use 2 or 3 as the first digit are sometimes three digits in length.
