shaah
A method that returns the Baal Hatanya's a shaah zmanis (temporal hour). This forms the base for the Baal Hatanya's day based calculations that are calculated as a 1.583 dip below the horizon after sunset. According to the Baal Hatanya, shkiah amiti, true (halachic) sunset, is when the top of the sun's disk disappears from view at an elevation similar to the mountains of Eretz Yisrael. This time is calculated as the point at which the center of the sun's disk is 1.583 degrees below the horizon. A method that returns a shaah zmanis (temporal hour) calculated based on the Baal Hatanya's netz amiti and shkiah amiti using a dip of 1.583 below the sea level horizon. This calculation divides the day based on the opinion of the Baal Hatanya that the day runs from netz amiti to shkiah amiti. The calculations are based on a day from sunriseBaalHatanya to sea level shkiah amiti. The day is split into 12 equal parts with each one being a shaah zmanis. This method is similar to , but all calculations are based on a sea level sunrise and sunset.
Return
the long millisecond length of a shaah zmanis calculated from netz amiti (sunrise) to shkiah amiti. If the calculation can't be computed such as in the Arctic Circle where there is at least one day a year where the sun does not rise, and one where it does not set, Long.MIN_VALUE will be returned. See detailed explanation on top of the AstronomicalCalendar documentation.
