Circadia is a 24-hour watch face built around the sun and moon where you actually are. The outer ring shows today's daylight and darkness, with dawn and dusk shaded through civil, nautical, and astronomical twilight. A white pointer marks the current time, so at a glance you can see how much daylight is left. Below the time, a small landscape shows the live sky. The sun and moon sit at their true positions for your location, rising, arcing across, and sinking into the horizon when they set. The moon is drawn at its actual phase, the dotted line traces today's path of the sun, and the mountains are lit from whichever side the light is coming from. Everything changes with the seasons: long summer days and short winter ones, high summer sun and low winter sun, even snow on the peaks in winter. Features 24-hour daylight ring with graded twilight and sunrise and sunset times Real sun and moon positions, calculated on the watch Moon phase and illumination Wrist raise: countdown to the next sunrise or sunset, twinkling stars, and the occasional shooting star Temperature (grays out when weather data gets old), date, battery, and a phone-disconnected indicator Optional seconds and AM/PM Always-on mode for AMOLED watches Settings Adjust seconds, twilight bands, the sun path, stars, shooting stars, horizon style, battery display, and more from Garmin Connect or directly on the watch (hold MENU → Watch Face → Customize). Location Circadia uses your location only to calculate sunrise, sunset, and sun and moon positions. It comes from your weather data or the last GPS fix and is stored only on your watch. You can also lock the face to a fixed location in settings. Inspired by Fair Circadian for Pebble by SetPebble.
