Signed Years Without Year 0
Although he used the usual French terms "avant J.-C." (before Jesus Christ) and "après J.-C." (after Jesus Christ) to label years elsewhere in his book, the Byzantine historian Venance Grumel used negative years (identified by a minus sign, −) to label BC years and unsigned positive years to label AD years in a table, possibly to save space, without a year 0 between them.
The XML Schema language, sometimes used in connection with representing data for storage in computers, contains built-in primitive datatypes, date and dateTime, which do not allow a year zero, and designate years BC as negative numbers. Years contain at least four digits. Thus -0001 in that language is equivalent to 1 BC. However, the defining recommendation indicates a change to a system similar to ISO 8601 and astronomical year numbering is likely in the future.

Famous quotes containing the words signed, years and/or year:
“You watched and you saw what happened and in the accumulation of episodes you saw the pattern: Daddy ruled the roost, called the shots, made the money, made the decisions, so you signed up on his side, and fifteen years later when the womens movement came along with its incendiary manifestos telling you to avoid marriage and motherhood, it was as if somebody put a match to a pile of dry kindling.”
—Anne Taylor Fleming (20th century)
“A few years before I lived in the woods there was what was called a winged cat in one of the farmhouses.... This would have been the right kind of cat for me to keep, if I had kept any; for why should not a poets cat be winged as well as his horse?”
—Henry David Thoreau (18171862)
“We hold on to hopes for next year every year in western Dakota: hoping that droughts will end; hoping that our crops wont be hailed out in the few rainstorms that come; hoping that it wont be too windy on the day we harvest, blowing away five bushels an acre; hoping ... that if we get a fair crop, well be able to get a fair price for it. Sometimes survival is the only blessing that the terrifying angel of the Plains bestows.”
—Kathleen Norris (b. 1947)
