Shubh Muhurat

In Indian culture, to start every work, the auspicious time has been decided on the basis of the current position of the planetary constellations. With the feeling that if you start the work at an auspicious time, the result of the work will be favorable. Often all the auspicious work of life like, marriage ceremony, yagyopaveet rites, grah shanti, grah-pravesh, Shodash rites etc. are considered in the auspicious time. In all the Muhurtas, the position of the constellations and auspicious yogas, the position of the antardasha and the transit of the present planets are given. For example, the Nakshatra prescribed in marriage and the value of Abhijit,

निर्वेधै: शशिकरमूलमैत्रपित्रय
ब्राह्‍मान्त्योत्तरपवनैः शुभो विवाह: ।
रिक्ताऽमारहिततिथौ शुभेऽह्नि वैश्व
प्रान्त्यांघ्रिः श्रुतितिथिभागतोऽभिजित्स्यात् ।।

In the Muhurtachintamani, about Jatkarma and Naamkaran muhurat on the birth of the person has been said that:

तज्जातकर्मादि शिशोर्विधेयं पर्वाख्य रिक्तोनतिथौ शुभेऽह्नि ।
एकादशे द्वादशकेऽपि घस्त्रे मृदुध्रुवक्षिप्रचरोडुषु स्यात् ॥
