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.
