Moon details

Current moon phase

The current moon phase is shown by name and as a large graphic at the top of the screen.

Changing the date and time

You can change the date and time shown by tapping the calendar icon on the top right of the screen. Even though the year isn’t shown in the date and time picker, Darkness does allow for setting the date to any year (so if you scroll past Dec 31, 2010, the date will be Jan 1, 2011).

Please note: the info shown in Darkness follows the date and time you’ve set, which may not be the current date and time.

Current Aziumth

The Current Azimuth is the azimuth for the moon at the currently chosen date and time (which might not be the actual current date and time). Azimuth refers to the angle between due north and the point on the horizon the moon is currently over.

Please note: The Current Aziumth for the moon uses your GPS location. If you’ve denied Darkness access to your current location, then the Current Aziumth will not be shown.

Current Altitude

The Current Altitude is the altitude for the moon at the currently chosen date and time (which might not be the actual current date and time). Altitude refers to the vertical angle measured from the horizon to the position of the moon. It will be a negative value if the moon is below the horizon. Altitude is commonly also called elevation or elevation above the horizon.

Please note: The Current Altitude for the moon uses your GPS location. If you’ve denied Darkness access to your current location, then the Current Altitude will not be shown.

Age

This is the amount of time that has past since the last new moon.

Illumination

This refers to the moon’s illumination as a percentage.

Distance

This is the distance of the center of the Earth to the center of the moon.

“The average centre-to-centre distance from the Earth to the Moon is 384,403 km, about thirty times the diameter of the Earth.” — Wikipedia

Definitely too far to walk.
