```Since Excel uses 1900-01-01 as day 1, the base date (or seed date) should be
1899-12-31.  But the base date actually calculates to 1899-12-30.

Well, I'll be darned !  The Excel serial date for 1901-01-01 is 367.  The
date for DATEVALUE(60) is 1900-02-29.

Excel calculates the year 1900 to be a leap year which, as Leif pointed out,
it isn't.

Chris,

It almost looks like a form of julian date based on 1900-01-01, but it
appears to be a couple of days off. In RPGIV, you could use SUBDUR and a
constant date value of 1899-12-30 to calculate this goofy julian. Of course
you want to specify the result in *D (days).

hth,
Eric DeLong

Can someone tell the formula to convert 20010318  to 36968.

This would be just like the DATEVALUE in Excel.

Thanks
Chris
