Most definitions I've found make no distinction between Julian Day Number & Date, other than the Julian Day starts at noon - so you need the time to get a correspondence between the day number & the date.

This site gives an alternative - 5 digits, the first 2 being the last two digits of the year & then a day number from 1-365(6).
