Class MoonPhase

java.lang.Object

org.shredzone.commons.suncalc.MoonPhase

public class MoonPhase
extends Object

Calculates the date and time when the moon reaches the desired phase.

Note: Due to the simplified formulas used in suncalc, the returned time can have an error of several minutes.

Method Details

compute

public static MoonPhase.Parameters compute()

Starts the computation of MoonPhase.

Returns:

MoonPhase.Parameters to set.

getTime

public ZonedDateTime getTime()

Date and time of the desired moon phase. The time is rounded to full minutes.

getDistance

public double getDistance()

Geocentric distance of the moon at the given phase, in kilometers.

Since:

3.4

isSuperMoon

public boolean isSuperMoon()

Checks if the moon is in a SuperMoon position.

Note that there is no official definition of supermoon. Suncalc will assume a supermoon if the center of the moon is closer than 360,000 km to the center of Earth. Usually only full moons or new moons are candidates for supermoons.

Since:

3.4

isMicroMoon

public boolean isMicroMoon()

Checks if the moon is in a MicroMoon position.

Note that there is no official definition of micromoon. Suncalc will assume a micromoon if the center of the moon is farther than 405,000 km from the center of Earth. Usually only full moons or new moons are candidates for micromoons.

Since:

3.4

toString

public String toString()

Overrides:

toString in class Object
