Calculations for solar time such as dawn, sunrise, sunset, dusk.
This is ‘solartime’, a Python module which calculates times for various positions of the sun: dawn, sunrise, solar noon, sunset, and dusk.
‘solartime’ is a vastly-simplified fork of Simon Kennedy’s ‘astral’ module, and is Free / Libre Open Source software under the Apache 2.0 license.
Its only dependency is the pytz package, and Python 2.6, 2.7, 3.3+.
>>> from datetime import date >>> from pytz import timezone >>> from solartime import SolarTime >>> >>> today = date(2014, 4, 20) >>> localtz = timezone('US/Eastern') >>> lat, lon = 38.0, -79.0 >>> >>> sun = SolarTime() >>> schedule = sun.sun_utc(today, lat, lon) >>> sunset = schedule['sunset'].astimezone(localtz) >>> print sunset 2014-04-20 19:56:38-04:00
