In the Brāhmaṇas, muhūrta denotes a division of time: 1/30 of a day, or a period of 48 minutes.[3] An alternative meaning of "moment" is also common in the Brāhmanạs.[4] In the Rigveda[5]muhūrta exclusively means, "moment".[6]
Each muhūrta is further divided into 30 kalā, (1 kalā = 1.6 minutes or 96 seconds). Each kalā is further divided into 30 kāṣṭhā (1 kāṣṭhā ≈ 3.2 seconds).
