Calculate Universal Time

Universal Time is the local time at 0 degrees latitude on Earth, otherwise known as Greenwich Mean Time and is calculated by adding the local time zone to the local time. As well, if daylight savings time is observed in the local time zone, the UT time will be one hour earlier.

`"UT" = "local time" + "time zone" + "daylight savings time"`

Calculate Ascendant

The Ascendant, from an astronomical point of view, is the value of the ecliptical geocentric longitude (aka Celestial Longitude λ) of the point of the ecliptic which is easterly on the horizon.

Ascendant `= arctan(y / x) = arctan((-cos(A)) / (sin(A)*cos(E) + tan(L)*sin(E)))`

where A is the local sidereal time in degrees, E is the inclination of Earth's equatorial plane to the ecliptic or obliquity of the ecliptic.

For values referred to the standard equinox J2000.0 use 23.4392911°, for J1950.0 use 23.4457889°.

L is the local latitude (Southern latitudes are negative, Northern positive).
