BigCal

A borderless floating calendar window with rounded corners, showing month, week, and year views with note management. BigCal’s height caps at the browser viewport. If the calendar grid has too many rows to fit on screen, the content area scrolls while the header stays fixed. The window re-constrains on browser resize.

Opening BigCal

Double-click the HUD or MiniCal
Use the API: CALENDARIA.api.showBigCal()
Scene controls button (if enabled in settings)
Automatically on world load (if “Show BigCal on Load” is enabled)

Display Modes

Month View

Default view. Displays a monthly grid:

Weekday headers with rest-day highlighting
Day cells showing notes, moon phases, and festival indicators
Multi-day events rendered as horizontal bars spanning weeks

All-day events displayed at the top of each column
Timed events positioned by start hour and duration
Recurring notes render on every matching day within the visible week
Multi-day events split into a timed start block, all-day middle days, and a timed end block; continuation edges drop their rounded corners so the bars read as contiguous across days

Each time cell (day:hour intersection) has a ”+” button for quick note creation at that specific hour

Year View

9-year overview grid for quick navigation:

Below the header, contextual indicators show:

Weather. Current conditions with icon and temperature (GM can click to open weather picker)
Season. Current season with icon and color
Era. Current era name (if calendar has eras configured)

Day Cells

Each day cell in month view shows:

Element	Description
Day number	Date, with today and the selected day each shown by a tinted cell background
Festival star	Indicates a festival day
Moon icons	Up to 3 visible, hover “+N” badge for additional moons; clickable for radial moon picker when >3 moons
Note indicators	Custom icons and colors for each note
Weather pill	Icon + temperature + wind direction for the day’s weather
Add button	Quick note creation (appears on hover)

Weather Pills

Day cells show weather as compact pills:

Today: Current weather (full opacity)
Past days: Historical weather from the weather history
Future days: Forecast weather (dimmed at 50% opacity)

Each pill shows weather icon, temperature, and wind direction.

Hover Tooltip: Hovering over a day cell shows:

Full date (Month Day, Year with era)
Festival name (if applicable)
Season name
Sunrise/sunset times
Weather conditions (icon, name, temperature, wind, precipitation)

Note listing. Festivals listed first with a star icon, then regular notes with colored dots matching each note’s color. Capped at 5 entries; extra notes show a “+N more” overflow indicator.

Interactions:

Click a day to select it (click again to deselect)
Right-click for context menu with notes (sorted alphabetically) showing inline edit/delete icons, plus BigCal-specific items (Settings, Open MiniCal, Close). Capped at 5 entries. Days with more than 5 notes show a “+N more” item that opens the Note Viewer pre-filtered to that date.
Right-click the BigCal window header to also open the context menu
Click a grayed-out day from another month to navigate there

Multi-Day Events

Events with duration span multiple days, rendered as horizontal bars across the calendar grid:

Color-coded with the note’s custom color
Show note icon and title
Arrow indicators mark events continuing from previous weeks
When multiple events overlap, bars condense to thin lines. On hover, they expand to full height showing icon and title with a smooth CSS transition.
Click any bar to open the note
Optional bookend markers indicate the start and end days of the event
Bars for timed multi-day events trim to the start hour on the first day and end hour on the last day, scaled against the active calendar’s hours and minutes per day. All-day notes and interior weeks of multi-week spans fill their cells edge-to-edge

Display Styles

Multi-day events render differently depending on their display style:

Style	Rendering
Icon	Default style. Event bar shows the note’s icon and title text across its duration span
Pip	Compact dot indicator. A minimal colored bar with reduced height for less visual weight
Banner	Full-width bar. A prominent colored bar emphasizing the event across its entire duration

Events sort by start date, then by display priority: banners first, then icons, then pips. Festival notes always sort above regular notes.

Shows previous week, current week, and next week
