Astronomical Year Numbering - Signed Years Without Year 0

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:

    Bernstein: “Girls delightful in Cuba stop. Could send you prose poems about scenery but don’t feel right spending your money stop. There is no war in Cuba. Signed Wheeler.” Any answer?
    Charles Foster Kane: Yes—Dear Wheeler, You provide the prose poems, I’ll provide the war.
    Orson Welles (1915–1985)

    The easiest way to get a reputation is to go outside the fold, shout around for a few years as a violent atheist or a dangerous radical, and then crawl back to the shelter.
    F. Scott Fitzgerald (1896–1940)

    The author’s conviction on this day of New Year is that music begins to atrophy when it departs too far from the dance; that poetry begins to atrophy when it gets too far from music; but this must not be taken as implying that all good music is dance music or all poetry lyric. Bach and Mozart are never too far from physical movement.
    Ezra Pound (1885–1972)
