The Days Tab: Prep, Shoot and Wrap

How the production calendar is built: day numbering across the three phases, week bands, date cascade, and day nicknames.

Every Day the Show Has

The Days tab is the spine of the production. Every other tab hangs off it: a call sheet belongs to a day, a DOOD column is a day, a hotel stay is drawn against days. A show is more than its shooting days, so prep and wrap are real rows people can be scheduled on rather than decoration drawn around the edge of the board.

Prep Counts Backwards

P1 is the day before Day 1. P2 is the day before that. Adding an earlier prep day gives you a new P4 and leaves P1, P2 and P3 exactly where they were. This matters more than it sounds: crew are already scheduled on those days, and renumbering them would move every DOOD cell attached to them.

Tip: Day 1 does not move when you add prep. Prep floats against the shoot rather than pushing it. The start date of the board changes instead.

Wrap Sits in Its Own Band

Wrap days are stored well past any real shoot length, so W1 is the same stored number whether the shoot ran 20 days or 60. Add a shoot day and nothing in wrap renumbers. Numbering wrap as "last shoot day plus one" would have looked tidier and would have quietly moved every wrap DOOD cell the first time a day was added.

Important: Never test whether a day number is greater than zero to find out if it is a shoot day. Off days are zero and wrap days are large positive numbers. The app has a dedicated check for this, and so should any spreadsheet you build off an export.

Two Ways to Print the Labels

Most shows say P1 and W1 out loud. Some count down to Day 1 and up from the last day, so prep reads -1 and wrap reads +1. Both describe the same stored day. Pick the one your show uses in Globals and every screen follows.

Tip: Shoot days always print as a bare number. Nobody on set says D12.

Week Bands

Weeks are banded above the grid and follow the phase. Prep weeks count backwards, so the week nearest the shoot is always Prep Wk 1 whatever gets added in front of it. Shoot weeks count forward from the week principal photography starts. Wrap weeks count forward from the last shoot day.

  • A prep day in the same calendar week as Day 1 still reads Prep Wk 1
  • Week 3 means the third week of principal photography, on every sheet already printed
  • Weeks break on Sunday

Dates and the Cascade

Change a date and G-Casper Pro offers to cascade. On a shoot day the days after it shift by the same amount. On a prep day the cascade covers the rest of prep and stops there, because moving a load-in day should not move the first day of shooting.

Important: Two days on the same date is allowed and sometimes deliberate, for A and B unit. The tab flags the duplicate so you know it is there. It does not stop you.

Day Nicknames

Any day can carry a nickname. Prep and wrap days need it more than shoot days do, because "P2" tells nobody that it is the tech scout. The nickname shows up on the day row, in the day selector, and on the call sheet where the layout has room for it.

Adding Days

The tab has a button for each phase. Prep days are added at the front, wrap days at the back, shoot days after the last one. Adding a week at a time is available from the same menu when you are laying out a full schedule by hand rather than importing one.

Tip: Most shows get their shoot days from a schedule import and add prep and wrap by hand afterwards. Movie Magic and USS files rarely carry them.
