The Zmanim library is an API for a specialized calendar that can calculate
different astronomical times including
sunrise and sunset and Jewish zmanim or religious times for prayers and other
Jewish religious dutuies. These classes extend GregorianCalendar and can therefore
use the standard Calendar functionality to change dates etc. For non religious astronomical / solar
calculations use the AstronomicalCalendar. The ZmanimCalendar contains the most common
zmanim or religious time calculations. For a much more
extensive list of zmanim use the ComplexZmanimCalendar.
This class contains the main functionality of the Zmanim library.

While I did my best to get accurate results please do
not rely on these zmanim for halacha lemaaseh
