Call me old- fashioned, but I think each of the working weeks used on a project by staff, should be reflected in calendars. I hardly ever work with a single calendar. Most I have seen in one portfolio is thirty-something, it was a four-continent job, with manufacturing plants running a variety of shift patterns in each country.
Yes, it is complex, that is why they need us! I think P6 does a better job than P3. The hours/days issue is much better handled.
In your example a client review calendar would have seven working days, even if the jobs that lead up to it are on a five-day calendar.
For a construction schedule I would use 5 or 6 day or mixed calendar if that is what they are working, but for a multi-year engineering I was leaning towards the 7 day calendar - and just noting it that way. At one of my last clients, I saw more planning & design schedules on 7 day schedules - I am not sure why but I kind of liked it, left the micromanagement to the PMs. When someone says 30 days I think "a month". 365 a year. And one of the most common specs out there is "21 Day Owner Review", which is 3 weeks. I know we all like to avoid it but claims are always in Calendar Days also. I would like to avoid mixed calendars - that tends too confuse the critical path and makes for float decimal complications, I don't think those were as much an issue in p3, a hassle in p6.
