The Role of Tithi in Vedic Jyotish, How to calculate the Tithi
A lunar day is called Tithi and these dates have special significance in a person’s life. There are total 30 lunar days or dates in a lunar month. Of these 30 Tithis, the first 15 are of Shukla Paksha and the remaining 15 are of Krishna Paksha. The moon is full on the 15th day of Shukla Paksha, hence this date is called Poornima. The 15th day of Krishna Paksha is called Amavasya, which means ‘to live together’ because on this day the Sun and the Moon form a union by living together. Amavasya is also called Nav-moon.
How to calculate the Tithi
The lunar month begins with a new moon. There is a Tithi of 12 degrees each in the conjunction of Sun and Moon, so it is very easy to find out. To calculate the date, the parts of the Sun are subtracted from the degrees of the Moon and divided by 12. For example, if the Moon’s degree is 290 and the Sun’s is 5 degrees, then we will do 290-5/12 to find the date, then we will get 23.75 which is equivalent to 24. In this way we easily know that there is 24th Tithi which is 9th Tithi of Krishna Paksha.
What does Tithi do (Tithi’s Role in Muhurtha)
The date has special significance to know what a person’s activity is related to the date’s activity. From date, the happiness and behavior of the doer or person is assessed. If the date is suitable and correct then the actions are in favor of the person and his behavior leads him to good results. Similarly, if the date is not suitable or good, then the work is not in favor of the person and the person has difficulty in getting the expected result and does not get good results, yet during this time the person is engaged in fulfilling the responsibilities because he has There was no other option.
Categorization of Tithis in Groups
These dates are divided into five groups namely Nanda, Bhadra, Jaya, Rikta and Poorna. Happiness is considered from Nanda Tithi, good fortune from Bhadra, victory from Jaya, emptiness from Rikata and perfection from Poorna. Nanda Tithi on 1st, 6th and 11th Tithi, Bhadra Tithi on 2nd, 3rd and 12th Tithi, Jaya Tithi on 3rd, 8th and 13th Tithi, Rikta on 4th, 9th and 14th Tithi ), and the fifth, tenth and fifteenth dates have been kept under Purna Tithi.
Lords of Tithis
These five groups of dates are ruled by five planets. Nanda Tithi is considered to be the factor of happiness, on which Venus rules. Bhadra Tithi is a factor of good luck and it is ruled by Mercury. Jaya Tithi is considered to be the factor of victory, Mars rules over it. Emptiness is considered from Rika Tithi and it is ruled by Shani. Similarly, fullness is considered from Poorna Tithi and on this the Guru’s rule runs.
Nature of Tithis
Each Tithi has its own distinct nature and the nature of these Tithis gives an idea of how a person will feel and behave during the activities on that Tithi. For example, if a person does any activity on the 4th Tithi then his behavior will be merciless, because the 4th Tithi comes in the blank group and this gives the idea of emptiness.
Lords-Devtas of Tithis
Tithis also have deities like planets and a tithi can have more than one deity. Auspicious work for any date is also calculated from its deity. As the deity of 14th (Chaturdashi Tithi) is Shiva, then this date is auspicious to finish any work. Similarly, the deity of the tenth date is Dharmaraja and this date will be auspicious for works related to law.
The mutual relationship of Nakshatra and Tithi
For successful completion of some programs, it is necessary to have a separate Nakshatra like Tithi, because some Tithi and Nakshatra are ruled by the same deity. For example, if it is appropriate to do any program in Jyeshtha Nakshatra, then it will be appropriate to do it on the seventh date as both are ruled by Indra.
