Get it on F-Droid

F-Droid GitHub release Build Status

Displays sunrise and sunset, twilights (civil / nautical / astronomical), blue and golden hour, solstices and equinoxes, moonrise and moonset, moon phases and illumination.

Suntimes Alarms
An alarm clock for Suntimes.

Suntimes Calendars
A calendar provider add-on for Suntimes.

The app:

  • displays the current time (system time zone, custom time zone, or solar time)
  • displays the time until the next rising/setting event.
  • displays the sunrise and sunset, blue and golden hour, and twilight times (civil / nautical / astronomical).
  • displays the current moon phase, illumination, moonrise and moonset times, and major phase dates.
  • displays the current sunlight and moonlight projected over a world map (basic equirectangular, blue marble).
  • displays the solstices and equinoxes, and notes the time until the next event.
  • displays the sun's current position, and its position at sunrise, sunset, and noon.
  • displays the moon's current position, and its position at moonrise and moonset.
  • includes an Alarm Clock that can set a repeating alarm or notification for the next sunrise or sunset (or other rising/setting event).
  • can display the configured location on a map (requires a map application) and configure the location from a map (using geo intent).

The app:

  • does not require GPS. The location is manually specified by default (and optionally obtained from GPS).
  • does not require network connectivity (or other unnecessary permissions). All calculations are performed locally on the device.

Widgets are (re)configurable:

  • location (latitude, longitude, elevation).
  • time zone (system / custom), or solar time (local mean time, apparent solar time).
  • user-defined titles (supporting limited substitutions).
  • misc. options: "use elevation", "show seconds", "show noon", and "show comparison", etc.

Widgets are themeable and provide:

  • a theme editor and support for basic custom themes.
  • a (default) dark theme (and dark w/ semi-transparent background).
  • a (default) light theme (and light w/ transparent background).

Widgets are resizable and include...

Clock widgets:

  • 1x1 digital clock widget that displays solar time (or a given timezone).

Sun widgets:

  • 1x1 sun widget that displays the sunrise or sunset time.
  • 1x1 sun widget that displays both sunrise and sunset times.
  • 1x1 sun widget that flips between sunrise and sunset times.
  • 2x1 sun widget that displays the sunrise and sunset times, and the difference in daylight between today and tomorrow (or yesterday).

Moon widgets:

  • 1x1 moon widget that displays moonrise and moonset.
  • 1x1 moon widget that displays next major phase.
  • 1x1 moon widget that displays phase and illumination (or phase only, or illumination only).
  • 2x1 moon widget that displays moonrise and moonset, phase, and illumination.
  • 3x1 moon widget that displays upcoming major moon phases.

Solstice widgets:

  • 1x1 solstice widget that tracks the upcoming solstice or equinox.

Position widgets:

  • 1x1 sun position widget that tracks the sun's altitude and azimuth.
  • 1x1 sun position widget that tracks the sun's declination and right ascension.
  • 3x1 sun position widget that displays the lightmap graph, and tracks the sun's altitude and azimuth (current, sunrise/sunset, and at noon).
  • 3x2 sun position widget that displays current sunlight and moonlight projected over a world map.
