Choose a calendar model
- Open Campaign Settings, then World.
- Enable the campaign calendar and choose a managed preset or Custom.
- Set the current date used by the top bar, date pickers, and #today editor shortcut.
- For a preset, decide whether Tapestry should manage its included holidays.
- Save World Settings before opening calendar tools.
Important
Changing a live calendar can change how existing dated content is interpreted. Export a JSON backup before restructuring months, eras, or leap rules.
Customize months, eras, and moons
Managed presets remain read-only. Switch the calendar to Custom when you need to edit its definition.
- Open Calendar, then Settings.
- Review weekday labels, month lengths, conditional months, and era naming.
- Add only the moons the campaign actively tracks and set their cycle information.
- Save the definition, then verify the current date is still valid.
Work with the timeline
- Open Calendar, then Timeline.
- Search by title or filter dated notes by entity type.
- Zoom and move through time to compare events across different periods.
- Select an entry to inspect its date and linked campaign record.
Best practice
Use Calendar for near-term play and Timeline for historical context. Date the source entity rather than duplicating the same fact in several places.
