What a Julian date means

The everyday "Julian date" printed on food packaging, military forms and batch codes is simply the day of the year: January 1 is 001 and December 31 is 365 (366 in a leap year). It is often written after a two- or four-digit year, so 27032 and 2027032 both mean February 1, 2027.

Astronomers use the Julian Day number instead: a continuous count of days since noon on January 1, 4713 BC, used to compare observations without worrying about calendars. Neither is the same as the Julian calendar, the Roman calendar that the Gregorian calendar replaced in 1582.
