Daysdate.vdm is a submacro that calculates the days between 2 dates. Return_value is set to
the number of days.

Needs access my leapyear.vdm submacro, which I have also posted.

Many years (actually decades) ago I wrote my own date library in c, however in vedit I just use the inbuilt Num_Eval_Date( )

I re-invented the wheel, it appears. Oh well, it was a fun macro to write.

I am not sure it is documented, but this command in VEDIT might help:

; JDate() - Return quasi Julian date for current date.
; JDate(date) - date = "mm.dd.yyyy".
; JDate(date,BEGIN) - date = "dd.mm.yyyy".
; JDate(date,REVERSE) - date = "yyyy.mm.dd".
; Accept any unique separator.
; Set Chars_Matched (0 for JDate and JDate()).

You can then insert a date with the Num_Ins_Date() command.
Therefore these commands:

#1 = jdate("01/01/1979")
num_ins_date(#1)

Will insert "01/01/1979" into the buffer.

This would calculate the number of days between two dates:

jdate("06/05/10") - jdate("01/01/1979")

BTW - I just noticed that my email replies to WebBoard are not working. Is anyone else having this problem?

Thanks Ted for the Julian Calendar tutorial.

Yes I am also having intermittant problems with the WebBoard. So far, I have been unable to isolate it.
