Hi Roman,

You could use a counter that updates every year and start in 36526 which
correspont to Jan/1/2000. Use a pulse or TimeOfDay as parameter for your
Today(logical) function. The week number is gonna be:
Mod((Today(logical) - 36526)/7)
This should work.

Sorry, In my previous message I used the wrong function. If you want to get
the number of week you have to get the integer of the division by 7 and not
Mod. So the expression should be:
int((Today(logical) - 36526)/7).

Carlos,

Your Expression assumes that the week starts on a Saturday (36526th day is
Saturday January 1st, 2000) but doesn't accommodate for it. So, to account
for the first week, the following Expression will work (for only a year though!):

((today(logical)-36520)/7)+1

Ciao!

Khalid
