Ephemeris – 24h Sun & Moon Dial

Ephemeris turns your watch into a daily almanac: a 24-hour solar dial showing the real arc of the sun and moon over your location, wrapped around a clean analog face with the data that matters day to day. THE SOLAR DIAL • The outer ring maps the full 24-hour day with noon at the top and midnight at the bottom — the sun marker arcs over the top of the dial exactly like the real sun: rises on the left, sets on the right. • Daylight and twilight bands are computed astronomically for your location, so the ring shows today's actual day length at a glance. The daylight arc is drawn heavier; white notches mark the exact sunrise and sunset points. • The next sun event with a countdown is written along the upper arc. • On solar models, a yellow halo grows around the sun marker with the current solar charging intensity. • The moon travels the same ring at its true position in the sky (from its right ascension), drawn with its live phase — new moon rides with the sun, full moon sits opposite. THE FACE • Analog hands with a second hand that ticks once a second, using power-friendly partial updates. On AMOLED watches the always-on screen switches to a stripped-back view — thin hands, a dim time and the sun's position — that respects Garmin's burn-in limits. • Big digital time, plus the time written out in words. • Accurate moon phase rendered with a true elliptical terminator. • Current weather icon, with temperature, wind and humidity in perception colors (blue when freezing, red when hot). Temperature and distance follow your watch's own unit settings. • Date, battery (fill turns red when low), steps with a goal arc, recovery hours, and your weekly running distance — switchable to cycling or a 7-day movement total. • Your next calendar appointment for today, under the hub. GOOD TO KNOW • The solar dial needs a location: after installing, the ring stays neutral gray until the watch has a GPS fix — starting any outdoor activity briefly is enough. • Weather and calendar data come from your paired phone via Garmin Connect. • Settings in the Connect IQ app: choose what the distance field shows (weekly running, weekly cycling, or a 7-day total of all movement), whether the dial puts noon or midnight at the top, the digital time format, the sun marker colour, and whether the second hand runs — turning it off saves battery.

AMOLED WATCHES NOW SUPPORTED Ephemeris runs on epix 2, epix 2 Pro (42/47/51 mm), fenix 8 43 mm and 47 mm, and fenix 8 Pro. On these watches the always-on screen switches to a stripped-back view — thin hands, a dim time and the sun's position on the ring — that stays well inside Garmin's burn-in limits. UNITS FOLLOW YOUR WATCH Temperature, wind and distance always showed metric before. They now match your watch's own settings, and temperature and distance are read separately — so Celsius with miles works if that is how you have it set. FOUR NEW SETTINGS In the Connect IQ app, alongside the existing distance field: • Digital time format — 24-hour, 12-hour, or match your watch • Dial orientation — noon at the top, or midnight • Second hand — turn it off to save battery • Sun marker colour — orange, red, yellow or white DAY NAME IN YOUR LANGUAGE The date line now takes the day name from your watch instead of always showing English. LAYOUT Recovery, distance and the humidity column no longer crowd each other on the right-hand side.
