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.

“As the Arab proverb says, “The dog barks and the caravan passes”. After having dropped this quotation, Mr. Norpois stopped to judge the effect it had on us. It was great; the proverb was known to us: it had been replaced that year among men of high worth by this other: “Whoever sows the wind reaps the storm”, which had needed some rest since it was not as indefatigable and hardy as, “Working for the King of Prussia”.”
—Marcel Proust (1871–1922)
