Calendaria
A system-agnostic calendar and time tracking module for Foundry VTT. Manage in-game dates, track moon phases, schedule events, and sync scene darkness with the time of day—and keep tabs on everything from a floating calendar.
Pre-Built Calendars
Calendaria ships with 15+ ready-to-use calendars including Greyhawk, Harptos (Forgotten Realms), Khorvaire (Eberron), Exandria, Barovia, Athas, Krynn, Golarion, and more. The Calendar Editor lets you build custom calendars or import from Simple Calendar, Fantasy-Calendar.com, Seasons & Stars, Simple Timekeeping, and Calendarium (Obsidian.MD).
