Drigganita (दृग्गणित; IAST: dṛggaṇita, from dṛk-gaṇita, "sight-calculation"), also called the Drik system, [1] is a system of astronomical computations followed by several traditional astronomers, astrologers and almanac makers in India. In this system the computations are performed using certain basic constants derived ...
Then Makara Sankranti would mark the beginning of Dakshinayana. However Makara Sankranti still holds importance in Hindu rituals. All Drika Panchanga makers like mypanchang.com, datepanchang, janmabhumi panchang, rashtriya panchang [4] and Vishuddha Siddhanta Panjika use the position of the tropical Sun to determine Uttarayana and Dakshinayana.

Hence the Indian national calendar (Rashtriya Panchang) published by the Government of India fully tallies with the almanac. However, the traditional school also has its validity. Jyotish Shastra is not astronomy, and it is based on the words of Parashara, Garga, Mantreshwara who never used computers or western astronomy. Further, the planetary ...
According to the Starwalk, the next planetary alignment will be visible on Feb. 28. There, stargazers will be able to view Saturn, Mercury, Neptune, Venus, Uranus, Jupiter and Mars in the evening.
Viewed from the same location, a star seen at one position in the sky will be seen at the same position on another night at the same time of day (or night), if the day is defined as a sidereal day (also known as the sidereal rotation period). This is similar to how the time kept by a sundial can be used to find the location of the Sun
The best time to see the planetary parade in January is during the first couple of hours after the Sun goes down, with Saturn and Venus appearing close to each other in the southwest, Jupiter high ...
In astronomy and celestial navigation, an ephemeris (/ ɪ ˈ f ɛ m ər ɪ s /; pl. ephemerides / ˌ ɛ f ə ˈ m ɛr ɪ ˌ d iː z /; from Latin ephemeris 'diary', from Ancient Greek ἐφημερίς (ephēmerís) 'diary, journal') [1] [2] [3] is a book with tables that gives the trajectory of naturally occurring astronomical objects and artificial satellites in the sky, i.e., the position ...
These texts provide specific information and formulae on motions of Sun, Moon and planets, to predict their future relative positions, equinoxes, rise and set, with corrections for prograde, retrograde motions, as well as parallax. These ancient scholars attempted to calculate their time to the accuracy of a truti (29.63 microseconds). In their ...
