Astral is a Python library for calculating the times of various aspects of the sun.

It calculates the following

Dawn
 The time in the morning when the sun is a specific number of degrees below the horizon.
Sunrise
 The time in the morning when the top of the sun breaks the horizon (asuming a location with no obscuring features.)
Solar Noon
 The time when the sun is at its highest point.
Sunset
 The time in the evening when the sun is about to disappear below the horizon (asuming a location with no obscuring features.)
Dusk
 The time in the evening when the sun is a specific number of degrees below the horizon.
Solar Azimuth
 The number of degrees clockwise from North at which the sun can be seen
Solar Elevation
 The number of degrees up from the horizon at which the sun can be seen
Rahukaalam
 "Rahukaalam or the period of Rahu is a certain amount of time every day that is considered inauspicious for any new venture according to Indian astrology".

Example

The following example demonstrates the functionality available in the module

import datetime
from astral import Astral

city_name = 'London'

a = Astral()
a.solar_depression = 'civil'

city = a[city_name]

print('Information for %s/%s
' % (city_name, city.country))

timezone = city.timezone
print('Timezone: %s' % timezone)

print('Latitude: %.02f; Longitude: %.02f
' %
 (city.latitude, city.longitude))

sun = city.sun(date=datetime.date(2009, 4, 22), local=True)
print('Dawn: %s' % str(sun['dawn']))
print('Sunrise: %s' % str(sun['sunrise']))
print('Noon: %s' % str(sun['noon']))
print('Sunset: %s' % str(sun['sunset']))
print('Dusk: %s' % str(sun['dusk']))

Produces the following output:

Information for London/England

Timezone: Europe/London
Latitude: 51.60; Longitude: 0.08

Dawn: 2009-04-22 05:12:56+01:00
Sunrise: 2009-04-22 05:49:36+01:00
Noon: 2009-04-22 12:58:48+01:00
