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)
“A few more years will destroy whatever yet remains of that magical potency which once belonged to the name of Byron.”
—Thomas Babington Macaulay (1800–1859)
“Material advancement has its share in moral and intellectual progress. Becky Sharp’s acute remark that it is not difficult to be virtuous on ten thousand a year has its applications to nations; and it is futile to expect a hungry and squalid population to be anything but violent and gross.”
—Thomas Henry Huxley (1825–95)
