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 women’s 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)
“And the immortal music of Chopin
Which we had been discovering for several months
Since we were fourteen years old. And coffee grounds,
And the wonder of hands, and the wonder of the day
When the child discovers her first dead hand.”
—John Ashbery (b. 1927)
“We are playing with fire when we skip the years of three, four, and five to hurry children into being age six.... Every child has a right to his fifth year of life, his fourth year, his third year. He has a right to live each year with joy and self-fulfillment. No one should ever claim the power to make a child mortgage his today for the sake of tomorrow.”
—James L. Hymes, Jr. (20th century)
