Gived an example of what your julian date looks like and what it should convert
to. Is it stored in a string field, or is it in two fields, one for the year
and one for the day?
Assuming that you only have the day number and no year; 123
DateSerial(Year(Date()),1,NumberofDays)
Assuming two character year and 3 character days and all years are in the 21st century
DateSerial(2000 + Val(Left(JulianDate,2)),1,Mid(JulianDate,3))
Assuming four character year and 3 character days and all years are in the
21st century
DateSerial(Val(Left(JulianDate,5)),1,Mid(JulianDate,5))
