At least as a format in DP, Julian is the correct term Julian dates are in the
form yyddd, where the ddd field is right-aligned and padded with zeroes (IBM
Dict. of Comp.) I don't know why you can't drop the year field if it isn't
relevant.

You may be thinking of the Julian calendar, which was superseded by the
Gregorian calendar. The later was introduced by Pope Gregory XIII in 1582, but
not immediately adopted everywhere. I do have a vague recollection of a dating
system that is an absolute count of days since some arbitrary day (22 April
4004 B.C?), of which the DP term is a loose extension. I think it is used
mostly in astronomy.
