"""Calculations for the position of the sun and moon.
The :mod:`astral` module provides the means to calculate dawn, sunrise,
solar noon, sunset, dusk and rahukaalam times, plus solar azimuth and
elevation, for specific locations or at a specific latitude/longitude. It can
also calculate the moon phase for a specific date.
The module provides 2 main classes :class:`Astral` and :class:`Location`.
:class:`Astral`
Has 2 main responsibilities
* Calculates the events in the UTC timezone.
* Provides access to location data
:class:`Location`
Holds information about a location and provides functions to calculate
the event times for the location in the correct time zone.
For example ::
>>> from astral import *
>>> a = Astral()
>>> location = a['London']
>>> print('Information for %s' % location.name)
Information for London
>>> timezone = location.timezone
>>> print('Timezone: %s' % timezone)
Timezone: Europe/London
>>> print('Latitude: %.02f; Longitude: %.02f' % (location.latitude,
... location.longitude))
Latitude: 51.60; Longitude: 0.05
>>> from datetime import date
>>> d = date(2009,4,22)
>>> sun = location.sun(local=True, date=d)
>>> print('Dawn: %s' % str(sun['dawn']))
Dawn: 2009-04-22 05:12:56+01:00
The module currently provides 2 methods of obtaining location information;
:class:`AstralGeocoder` (the default, which uses information from within the
module) and :class:`GoogleGeocoder` (which obtains information from Google's
Map Service.)
To use the :class:`GoogleGeocoder` pass the class as the `geocoder` parameter
to :meth:`Astral.__init__` or by setting the `geocoder` property to an
instance of :class:`GoogleGeocoder`::
>>> from astral import GoogleGeocoder
>>> a = Astral(GoogleGeocoder)
or ::
>>> from astral import GoogleGeocoder
>>> a = Astral()
>>> a.geocoder = GoogleGeocoder()
