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.

“I remember a very important lesson that my father gave me when I was twelve or thirteen. He said, You know, today I welded a perfect seam and I signed my name to it. And I said, But, Daddy, no ones going to see it! And he said, Yeah, but I know its there. So when I was working in kitchens, I did good work.”
—Toni Morrison (b. 1931)
“Not so many years ago there there was no simpler or more intelligible notion than that of going on a journey. Travelmovement through spaceprovided the universal metaphor for change.... One of the subtle confusionsperhaps one of the secret terrorsof modern life is that we have lost this refuge. No longer do we move through space as we once did.”
—Daniel J. Boorstin (b. 1914)
“Jerry: Shes one of those third-year girls that gripe my liver.
Milo: Third-year girls?
Jerry: Yeah, you know, American college kids. They come over here to take their third year and lap up a little culture. They give me a swift pain.
Milo: Why?
Jerry: Theyre officious and dull. Theyre always making profound observations theyve overheard.”
—Alan Jay Lerner (19181986)
