Guard Post Duty Roster and Monthly Attendance Grid

Guard Post Duty Roster and Monthly Attendance Grid is an offline app (one HTML file in a zip) for a site supervisor or control room. You list posts and shifts and say how many people each post needs on each shift. You then assign named people to each post and shift on each date. A cover board shows, for every post and day, people assigned over people needed, with the short ones in red. A day sheet lists today's duties with one-tap attendance marks, and a monthly grid collects the marks for printing.

The problem it removes: A post is found short only when it is already short, a person is put in two places at once, someone marked on leave is still on the roster, and at month end the attendance sheet is rebuilt by hand from memory and scraps of paper. This app shows the shortfall while the roster is being made and keeps the attendance marks in one grid.

What is inside:

• Cover needed: how many people each post needs on each shift, optionally only on some weekdays
• Cover board: a grid of posts and shifts against the days of the month showing people assigned over people needed, short cells in red, with a tap to choose who is on duty
• Copy a week of duties to another week with a preview, then change only the days that differ, with Undo
• Duty roster by person: each person against the days of the month with the shift code and post, and overlapping duties outlined
• Day sheet: today's duties by post and shift with one tap Present, Late, Absent, Leave, Sick or Off marks, and a button to mark everyone left as present
• Monthly attendance grid with a count of each mark per person, days with a duty but no mark, and the share of marked days present or late
• Checks for short posts, short posts once absences are counted, overlapping duties, and people on duty while marked absent, leave, sick or off
• Printable A4 landscape duty roster and monthly attendance grid with signature lines
• 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: site supervisors, security company control rooms, facilities and building services managers, and anyone who must keep named people on posts around the clock and keep a monthly attendance record for them.

What it is NOT: It records who is rostered and what a supervisor marks. It does not clock people in, track locations, calculate pay or overtime, apply any labour law or contract rule, or send the roster to staff. Print it or save it as a PDF and share it yourself. 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 (186 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 186 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).
