Watch the sun and moon arc across a realistic sky dome, or choose from compact displays for minimal screen space. The HUD provides at-a-glance time, weather, and event information.

Use bundled calendars (Gregorian, Harptos, Exandria, Golarion, and more) or create your own with the Calendar Editor. Supports custom months, weekdays, leap years, intercalary days, and year zero handling.

Schedule notes and events with recurrence patterns: daily, weekly, monthly, yearly, or advanced options like moon phases, seasons, linked events, and computed dates (Easter, lunar new year, etc.).

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

Generate weather based on climate zones and seasons. Sync scene ambience to time of day with smooth transitions at sunrise and sunset.

Define historical eras with custom year formatting (1492 DR, Year 5 of the Third Age) and repeating cycles (zodiac signs, elemental weeks).
