Muhurta (Sanskrit: मुहूर्त) is a Hindu unit of measurement for time in the Hindu calendar . A Muhurta equals 2 Ghadiyas or approximately 48 minutes. It is stated in Manu Samhita that eighteen nimeshas (twinklings of the eye, are one kashtha), thirty kashthas one kala, thirty kalas one muhurta, and as many (muhurtas) one day and night.
Traditionally, it is common practice amongst Hindus to start or avoid starting significant tasks like religious ceremonies, etc on the basis of the quality of a particular Muhurta. The Vedic scriptures also generally recommend one or more Muhurtas to perform rituals and practices. Some examples are as follows
