Dates in different formats

[GARY]

How do I compute the number of months between a date in the mm/dd/ccyy
format (such as 03/12/2002) and a date in the Julian date format (such
as 2009341)?

You can convert the Julian date to Excel format, and then use it with
the other date in a DATEDIF formula. Take a look at Chip Pearson's
site:

Hope this helps.

If the dates are in A1 and B1 respectively, the formula is
=DATEDIF(A1,DATE(LEFT(B1,4),1,0)+RIGHT(B1,3),"m")
