500 (D) was a leap year starting on Saturday of the Julian calendar, the 500th year of the Common Era (CE) and Anno Domini (AD) designations, the 500th year of the 1st millennium, the 100th and last year of the 5th century, and the 1st year of the 500s decade. As of the start of 500, the Gregorian calendar was 1 day ahead of the Julian calendar, which was the dominant calendar of the time.
It is one of only seven years to use just one Roman numeral. The seven are 1 AD (I), 5 AD (V), 10 AD (X), 50 AD (L), 100 AD (C), 500 AD (D), and 1000 AD (M).
