Try this in BizTalk map via an inline C# scripting functoid
public static string ToJulian(string strdateTime)
DateTime dateTime = Convert.ToDateTime(strdateTime);
int day = dateTime.Day;
int month = dateTime.Month;
int year = dateTime.Year;
if (month < 3)
month = month + 12;
year = year - 1;
long dt = day + (153 * month - 457) / 5 + 365 * year + (year / 4) - (year / 100) + (year / 400) + 1721119;
return dt.ToSTring(dt);
or this returns long, and the input parameter is datetime
public static long ToJulian(DateTime dateTime)
int day = dateTime.Day;
int month = dateTime.Month;
int year = dateTime.Year;
if (month < 3)
month = month + 12;
year = year - 1;
return day + (153 * month - 457) / 5 + 365 * year + (year / 4) - (year / 100) + (year / 400) + 1721119;

Following in the what we have been using in our maps, this has two static methods. One for standard datetime to Julian and another to convert Short datetime to Julian:
public int ToJulian(string dt)
try
DateTime date = DateTime.Parse(dt);
return ((date.Year - 1900) * 1000) + date.DayOfYear;
catch
return 0;
/// <summary>
/// Convert to Julian from dd/mm/yy
/// </summary>
/// <param name="dt"></param>
/// <returns></returns>
public int ToJulianFromShortDT(string dt)
try
DateTime date = new DateTime(int.Parse(dt.Substring(6, 2))+2000, int.Parse(dt.Substring(3, 2)), int.Parse(dt.Substring(0, 2)));;
return ((date.Year - 1900) * 1000) + date.DayOfYear;
catch
return 0;
