Suntimes

Android app (and widget collection) that displays sunlight and moonlight times for a given location.

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

The app:

• displays the current time (system timezone, custom timezone, or solar time), and notes 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 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.
• can set an alarm 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).
• timezone (system / custom), or solar time (local mean time, apparent solar time).
• user-defined titles (supporting limited substitutions).
• misc options: "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/ transparent background).
• a (default) light theme (and light w/ transparent background).

Widgets are resizable and include...

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).

Additional screenshots can be found on the project wiki and in the gh-pages branch.
