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.

“They will tell you tough stories of sharks all over the Cape, which I do not presume to doubt utterly,—how they will sometimes upset a boat, or tear it in pieces, to get at the man in it. I can easily believe in the undertow, but I have no doubt that one shark in a dozen years is enough to keep up the reputation of a beach a hundred miles long.”
—Henry David Thoreau (1817–1862)
“The liberal wing of the feminist movement may have improved the lives of its middle- and upper-class constituency—indeed, 1992 was the Year of the White Middle Class Woman—but since the leadership of this faction of the feminist movement has singled out black men as the meta-enemy of women, these women represent one of the most serious threats to black male well-being since the Klan.”
—Ishmael Reed (b. 1938)
