Calendar

The calendar is where most of the work starts: every planned maintenance window appears on it, and the event card, the checklist and the new schedule all open from it.

The five views

The view is chosen in the top toolbar, and each one answers a different question.

View	What it answers
Daily	What is happening today, hour by hour
Weekly	Where the windows fall in the week, and where they overlap
Monthly	Which days are busy, and at what hour of the day
Quarterly	Three months side by side — where the freezes are and where the load is
Yearly	Twelve months as a heat map of load alone

An administrator sets the Default calendar view in settings. That list holds four views — Monthly, Weekly, Quarterly and Yearly; the daily view is reached by clicking a day number or with its keyboard shortcut. Choosing a view by hand during a session wins over the default.

What a cell shows

The week starts on Sunday in both languages, and the weekend is Friday and Saturday.

In the monthly view each cell shows up to three event chips and then +N more. Below them runs a 24-hour track: every window is painted on it at its real hour. That is what turns a whole month into a single picture — a flat rail on most days, and two adjacent blocks near the end of the day on the ones where work actually happens. The same track appears in the quarterly view.

A day carrying a configuration freeze or a holiday spends one row on that name, and therefore shows one chip fewer — the marker is the more expensive fact to miss.

Filtering: dim or remove

Filtering by update type is done from the Filter button in the toolbar. What is currently filtered appears as chips below it, next to Clear all, and that strip appears only when something is genuinely filtered. The behavior differs by view, deliberately:

• Daily · Weekly · Monthly — a non-matching event is dimmed, not hidden. The screen says so: "Events that do not match are dimmed, not hidden." An event that vanishes from a grid reads as data loss.
• Quarterly · Yearly — here there is no chip to dim, only a five-pixel segment on the track, and a dimmed segment is an invisible one. So these two views genuinely filter.

Cancelled events are hidden by default. Show cancelled events has to be turned on in order to permanently delete an event that was opened by mistake.

The context panel

The panel opens from the toolbar and holds five cards over the same date range the calendar is showing:

Card	What is in it
Now and next	The window running right now and the next one within 30 days, with Mark as completed and Report a failure straight from the card
Load in range	A count per status, a breakdown by weekday, and a breakdown by update type that filters the calendar when clicked
Window risks	Collisions, overlap with a configuration freeze, windows that ended and stayed open, windows with no service ticket, and windows falling on a holiday
Upcoming freezes and holidays	Active and planned freeze periods, and holidays in range
Maintenance debt	How many servers are past due with no window scheduled

Maintenance debt loads only on click. The figure needs a full inventory scan, and the card says so rather than paying that price every time the calendar opens.

When a check is unavailable, the window-risks card states that the list is partial and which check is missing — it does not present a short list as if it were complete.

Keyboard shortcuts

The shortcuts work when no field has focus and no event card is open.

Key	Action
1 · D	Daily view
2 · W	Weekly view
3 · M	Monthly view
4 · Q	Quarterly view
5 · Y	Yearly view
T	Back to today
J · N	Next period
K · P	Previous period
C	New schedule (for anyone allowed to create an event)
R	Open and close the context panel

The arrow keys follow the direction time runs on screen: in Hebrew the next period is to the left, in English to the right. The same logic governs the navigation chevrons in the toolbar.

Out of the calendar

Clicking an event chip opens the event card — details, checklist and tasks in three tabs. Clicking a day number enters the daily view. Hovering a cell reveals New schedule on this day for administrators, which opens the scheduling wizard with the date already filled in and a default 01:00–05:00 window; the same button, labeled Schedule on this day, also sits at the bottom of the +N more panel.
