I have a ??? reguarding build dates.. If the month starts on the Thursday does the fist week ( A ) end on a Saturday and the 2nd week ( B ) starts on that Sunday or does the first week end in 7 days on the following Wendsday... Sorry if this sounds stupid..

You got it!:thumbsup:

I got it ? the first part or the 2nd part?

Yes. :)

There are no absolutes in how Fisher did their weeks. It varied some.
