Anno Scribere (in the Year of Writing) is a calendar era where year 0 is placed at 3201 BC, near the invention of Cuneiform, the earliest known script. It was created to be used as an alternative to the Julian and Gregorian calendars' eras of Before Christ / Anno Domini, also known as the Common Era. The calendar's secondary aim as an alternative to the Holocene calendar—which places 10000 BC as its first year—is to delay the prevalence of 5 digit years, which are cumbersome to pronounce.

Non-presice years before 1 AD that end with zero should always end with a zero or zeroes in AS (e.g. c. 2500 AS / 700 BC). Years before 0 AS are to use the denomination Common Prehistory (CPH) (e.g. 441 CPH). The period starting in 0 AS is called Postcommon Prehistory in areas that had yet to develop a script.
