Calendaria

Your campaign's time deserves more than a number in the corner. Calendaria gives your world a calendar and clock, with an animated HUD that tracks the sun and moons and dims scenes at night. Schedule notes that fire on conditions like "every full moon", roll weather across seasons and zones, and jump ahead with a table-wide cinematic time-skip.

Highlights

Animated time display

Watch the sun and moon arc across a sky dome, or pick a compact display for minimal screen space. The HUD shows time, weather, and event information at a glance.

Custom calendars

Use a bundled calendar or build your own with the Calendar editor. Define custom months, weekdays, leap years, intercalary days, and year-zero handling.

Smart events

Schedule notes and events with recurrence patterns: daily, weekly, monthly, and yearly. Advanced patterns trigger on moon phases, seasons, linked events, and computed dates.

Multi-moon support

Track multiple moons with independent cycle lengths, phases, and colors. Trigger events on specific lunar phases.

Weather and ambience

Generate weather by climate zone and season. Sync scene ambience to time of day, with transitions at sunrise and sunset.

Eras and cycles

Define historical eras with custom year formatting and repeating cycles.
