Thanks a lot ( I had to adapt it to French - " ; " instead of "," and to
translate key words)
and it's OK

* it's APRIL - month is 4 but we had 4-1 monthes since Year begun. So.. 3

* want to have the the fraction of the current month : last day 30,
first
1,
number of day in this month 30-1 +1, gives 30.

* imagine we are the 6 of Apr. this gives 6/30=0.2
so month since Jan 1 is 3.2

HOW to automatize this day by day. I mean if I came back on the
worksheet
in 2 weeks or 3 monthes I want the logics to know this at any time for
any
date. This suppose to be able to determine the current month, then
process
it's number of days, the the fraction, only knowing TODAY ( )


thank you
