Nityayoga
In Indian astronomy, ''yoga'' (also called ''nityayoga'') is a period of time, of varying lengths, during which the sum of the ''nirayana'' longitudes of the Sun and the Moon increases by an amount of 13 degrees 20 minutes (or, equivalently, 800 minutes). While considering the sum, when the sum is 360 degrees or more, then the angle 360 degrees is subtracted from the sum to make the sum an angle between 0 degree and 360 minutes. Consider a moment T1 when the sum of the longitudes of the Sun and the Moon is 0 degree and let T2 be the next immediate moment when the sum of the longitudes of the Sun and the Moon is 13 degree 20 minutes. The duration of time between the moments T1 and T2 is the first ''yoga''. Similarly, let the next immediate moment when the sum of the longitudes of the Sun and Moon is 26 degrees 40 minutes. The duration of time between the moments T2 and T3 is the second ''yoga''. The third, fourth and higher ''yoga''-s are defined in a similar way. Since 27 X 13 degr ...

Vāra (astronomy)
In Indian calendrical systems, vāra (or, vāsara) denotes the Names of the days of the week, week-day. It is one of the five elements that constitute the traditional almanacs called ''Panchangam, Pañcāṅga''-s the other four being ''Nakshatra'', ''Tithi'', ''Karana (pancanga), Karaṇa'' and ''Nityayoga''. (Translated by R. V. Vaidya from Marathi originally published in 1896.) The concept of week, the unit of time consisting of seven days, is indigenous to Indian civilisation. The concept was probably borrowed by Babylonians and its use predates the use of the twelve zodiacal signs in Indian civilazation. The concept finds mention in Atharva Veda. The seven week-days are named after the seven classical planets as in the ancient Greek and Roman traditions. The rationale behind the naming of week days The historical rationale behind the current naming of the week-days is astrological in origin and it can be summarized as given below.
