How do I convert a Julian date into a regular date?
 

I have a long list of Julian dates that are formatted as follows:
3300
1296
0346

The first number is the year, i.e. 2003, 2001, 2000.
The next three numbers are the numeric equivalent of where that date falls
in the year, i.e. 300=Oct 27, 296=Oct 23, and 346=Dec 12.

Excel talks about how to convert to a Julian date, but I have not found how
to go from a Julian date to a regular date that I am used to seeing.

Many thanks,

Jessica Nelson

=DATE(2000+LEFT(A1),1,RIGHT(A1,3)+0)

=DATE(IF(0+(LEFT(A1,1))<30,2000,1900)+LEFT(A1,1),1 ,RIGHT(A1,3))

Although for 0346 I get December 11th, 2000

Probably due to 2000 being a leap year.

For more on working with Julian dates see Chip Pearson's site. The formula
above is modified from one of his.

... 0+(LEFT(A1,1))<30 ...

Uh, what could be in A1 that would make that False? :-))
