Time planing with night-work

[Andriy Gritsenko]

I need to plan full-day work with two periods.
First work period start at 08:00 and finish at 20:00
Second work period start at 20:00 and finish at 08:00 on the next day.

In special calendar whithout dificults I can determine only first work
period. With second work period I have a problem: Project system say to me
"time of finish period could not be early time of start same period".

How I can to determine correctly night-work period?

The times on the calendar ar the work hours on that particular day and don't
necessarily represent a continuous work period.

There are a couple of things involved in your situation. First of all, you
need two seperate calendars, one for each shift. The first one is easy,
work begins at 08:00 and ends at 20:0. Don't ignore the meal break time -
leaving it out introduces a signifigant error in the computation of the
amount of work you'll accomplish in a workday! If you have 2 30-minute
breaks during that 12-hour shift, your hours of work might read 08:00-12:00,
12:30-16:30, 17:00-20:00, reflecting that out of the 12 hours your workers
are on the property they actually do 11 man-hours of work.

Your second calendar requires a little more thought. You have a shift that
comes in at 20:00 and goes home at 08:00. Consider what happens on Monday.
Your shift comes in at 20:00. But Monday ends at 00:00 midnight - the work
those people do after midnight is actually being done on Tuesday morning.
So the their calendar would show 4 hours of work, 20:00-00:00 on Monday and
8 hours of work, 00:00-08:00, on Tuesday. Now no one on the shift works
during the day on Tuesday but they come back on Tuesday night at 20:00. So
there's a second block of hours on Tuesday representing the people that come
in on Tuesday night and go home on Wednesday morning. The portion of that
shift that is on Tuesday is 20:00-00:00. Thus your calendar would show Mon
20:00-00:00, Tue 00:00-08:00 and 20:00-00:00, Wed 00:00-08:00 and so forth
through the week.
