The time zone is either the local time zone of the default location or the
Universal Time (Greenwich Mean Time). Events are calculated for 0:00 of the
The ephemeris can be shown in western or vedic mode. Differences between these
two modes are
- The list of planets is according to the configuration in Vedic resp. western astrology.
- The order of the planets is different: western mode has the astronomical
order, Vedic mode has the week day order.
- Ayanamsa is calculated according to configuration for western/Vedic Ayanamsa.
- Nodes may be different, too (-according to configuration of true/mean node
for western/Vedic mode).
The graphical representation can be configured for different circle types (similiar to Unranian astrology).
Sunrise and Sunset
Sunrise and sunset are always calculated for the default location. Even the time
zone UT has the corrdinates of the default location.
Sunrise and sunset can be configured in the Configure Ephemeris tab of the configuration dialog.
This view calculates the ingress times of the objects. Western and Vedic show sign changes. Vedic view shows Nakshatra changes, too.
Tithi and Lunar Events
Tithis and lunar events are based upon the position of the Sun and the Moon, resp.
the angle from Sun to Moon.
Western astrology pays attention to the classical aspects, e.g. conjunction for
New Moon or opposition for Full Moon.
Vedic astrology divides the month (i.e. the time between 2 New Moon events) into
30 equal parts, each of 12 deg.
The first half is the bright part of the month (Sukla Paksha), the second half
is the dark half of the month (Krishna Paksha).
Remark: The Tithi of a day is defined to be the Tithi at sunrise. So
a birth before sunrise has the Tithi of the day before!
Krishnamurti Paddhati (K.P.) Events
K.P. events are are based upon the position of the Moon in her Nakshatras (Lunar
mansions, stellar constellations).
Each Lunar position has a K.P. lord and sublord. These lords change from time to
time, e.g. on a Nakshatra change of the Moon. The K.P. event view of Maitreya's
ephemeris view calculates these events.
Classical K.P. astrology uses only Vimsottari Dasa. But the program
calculates K.P. events for general Nakshatra Dasas, too. This feature is intended
for research purposes.
