With the advancement in technology, Ephemeris today is calculated electronically with the help of mathematical models based on the movement of celestial bodies via-a-vis that of the Earth. The printed Planetary Ephemeris, though obsolete, is still in use in some parts of the world where the computers and electronic devices are still not widely used or haven’t been made available to the public at large.

Further, the Planetary Data column depicts Ingresses (planetary sign changes) and Stations (planetary changes of direction, whether direct or retrograde). An ephemeris (plural: ephemerides) (from the Greek word ephemeros= daily) is a table providing the positions (given in longitude) of the Sun, the Moon, and the planets in the sky along the zodiacal ecliptic at a given moment in time; the positions are usually given for either noon or midnight depending on the particular ephemeris that is used.

Since ancient times, the current planetary positions on a given date (Grah position or Grah Stithi) have been assigned printed values in a tabular format. These attributes tend to change from time to time with the change in the trajectory of the celestial bodies. As a result, such a tabular compilation would usually last for a day only to be replaced by new values on the following day. Such a diary was, therefore, termed as Planetary Ephemeris.
