Event Run Sheet and Timeline Printer with Version Control

Event Run Sheet and Timeline Printer with Version Control is an offline app (one HTML file in a zip) for an event manager. You list your team once. For each event you add a crew list with call times and a run of cues: the time, how long it takes, where, and who owns it. On the day the Today board shows each cue as Pending, Done or Delayed. Each time the plan changes you issue a new version and print again.

The problem it removes: The team works from different versions of the timeline. A cue is moved by ten minutes in a chat and the stage manager never sees it. One person is given the sound check and the guest welcome at the same time, and nobody notices until the day. This app keeps one timeline, checks it for clashes and prints it in time order with a version number on it.

What is inside:

• Events with date, venue, team call time, a version number, the date it was last revised and a note of what changed
• Run items with start time, duration, calculated end time, area, owner, phase and status, with a rule that stops one person having two overlapping cues
• A rule that stops a cue being given to someone who is not on the crew list of that event
• Crew list per event with role on the day, call time and phone, printed on the cover sheet
• Today page and a status board (Pending, Done, Delayed) for the cues of the day, plus a count of cues with no owner
• Run sheet list sorted by date and time with filters by event, owner and phase, printed from one button, and a cover sheet for each event
• Example data you can load in one click, a Start here guide and an Honest limits panel
• JSON backup and restore, CSV export, and CSV import with a check of every row before anything is added

Who it is for: event managers, wedding and corporate event planners and venue operations teams who run events with a crew and a minute by minute plan, and want one printed version of it.

What it is NOT: It does not send the run sheet to the team or notify anyone about a change. It has no guest list, seating, budget or supplier payments, no drag and drop timeline and no clock that moves cues by itself. The cover sheet does not replace contracts or safety plans. It is not legal, tax or accounting advice, it is not connected to any government system, bank or messaging service, and it does not file or send anything by itself. UAE e-invoicing is not part of it.

Verified by us: scripted tests in Chromium (148 checks through the real screens: adding, editing and deleting records in every table, required-field messages, backup then clear then restore, CSV export then import, keyboard order, print layouts rendered to PDF, no horizontal scrolling at 375 and 1280 pixels, no network requests) and an independent recalculation by a separately written Python evaluator of 1082 calculated values (25 randomised rows plus the example data) with 0 mismatches. Safari engine (WebKit): smoke test passed; Firefox: could not be launched. Not tested: Firefox beyond what is stated here, and no real printer was used (print layouts were checked as PDF).
