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:
“My fellow Americans, I am pleased to tell you today that I’ve signed legislation which outlaws Russia forever. The bombing begins in five minutes.”
—Ronald Reagan (b. 1911)
“The expansive nature of truth comes to our succor, elastic, not to be surrounded. Man helps himself by larger generalizations. The lesson of life is practically to generalize; to believe what the years and the centuries say against the hours; to resist the usurpation of particulars; to penetrate to their catholic sense.”
—Ralph Waldo Emerson (1803–1882)
“In some withdrawn, unpublic mead
Let me sigh upon a reed,
Or in the woods, with leafy din,
Whisper the still evening in:
Some still work give me to do,—
Only—be it near to you!
For I’d rather be thy child
And pupil, in the forest wild,
Than be the king of men elsewhere,
And most sovereign slave of care:
To have one moment of thy dawn,
Than share the city’s year forlorn.”
—Henry David Thoreau (1817–1862)
