tzais26Degrees
Deprecated
This method should be used <em>lechumra</em> only since it returns a very late time, and if used <em>lekula</em> can result in <em>chillul Shabbos</em> etc. There is no current plan to remove this method from the API, and this deprecation is intended to alert developers of the danger of using it.
This method should be used lechumra only and returns tzais based on when the sun is 26 below the horizon.For information on how this is calculated see the comments on alos26Degrees. Since the zman is extremely late and at a point when it is long past the 18 point where the darkest point is reached, it should only be used lechumra such as delaying the start of nighttime mitzvos.
Return
the Date representing the time. If the calculation can't be computed such as northern and southern locations even south of the Arctic Circle and north of the Antarctic Circle where the sun may not reach low enough below the horizon for this calculation, a null will be returned. See detailed explanation on top of the AstronomicalCalendar documentation.
