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:
“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 one’s going to see it!” And he said, “Yeah, but I know it’s there.” So when I was working in kitchens, I did good work.”
—Toni Morrison (b. 1931)
“The child-rearing years are relatively short in our increased life span. It is hard for young women caught between diapers and formulas to believe, but there are years and years of freedom ahead. I regret my impatience to get on with my career. I wish I’d relaxed, allowed myself the luxury of watching the world through my little girl’s eyes.”
—Eda Le Shan (20th century)
“If all the year were playing holidays,
To sport would be as tedious as to work;
But when they seldom come, they wished for come,
And nothing pleaseth but rare accidents.”
—William Shakespeare (1564–1616)
