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)
“... it is only after years and years that you can speak of penury in the midst of opulence, of hunger in the midst of almost sinful plenty. You must never speak of the immediate experience unless and until you have learned its consequent value. Otherwise you grow old in bitterness which is barren and futile....”
—E. M. Almedingen (b. 1898–?)
“‘He hardly drinks a pint of wine,
And that, I doubt, is no good sign.
His stomach too begins to fail:
Last year we thought him strong and hale,
But now, he’s quite another thing;
I wish he may hold out till spring.’
Then hug themselves, and reason thus;
‘It is not yet so bad with us.’”
—Jonathan Swift (1667–1745)
