Calculations for the position of the sun and moon.
Project description
Welcome to Astral V0.5
Astral is a python module for calculating the times of various aspects of the sun and moon.
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”.
- Moon Phase
Calculates the phase of the moon for a specified date.
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\n' % (city_name, city.country)) Information for London/England >>> timezone = city.timezone >>> print('Timezone: %s' % timezone) Timezone: Europe/London >>> print('Latitude: %.02f; Longitude: %.02f\n' % \ >>> (city.latitude, city.longitude)) Latitude: 51.60; Longitude: 0.08 >>> 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'])) 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 Sunset: 2009-04-22 20:09:07+01:00 Dusk: 2009-04-22 20:45:52+01:00
Access to the database of cities can be made through the Astral class:
>>> a = Astral() >>> db = a.citydb >>> london = db['London']
Timezone groups such as Europe can be accessed via attributes on the database:
>>> a = Astral() >>> db = a.citydb >>> europe = db.europe.cities >>> europe.sort() >>> europe ['Aberdeen', 'Amsterdam', 'Andorra la Vella', 'Ankara', 'Athens', ...
