ok thanks, and now a simpler question.

1- i created the calendar as you described but now how can i use that calendar?

2-i had entered days into my schedule before creating this calendar.

now when i start using this calendar, does it mean those days wil appear the same but will mean 7 day calendar days? or will i have to multiply the previous days i entered by 5/7 to convert to 7 day work weeks?

and the new days will mean based on 7 days only i assume
