Muhūrta is a Hindu unit of time along with nimiṣa, kāṣṭhā, and kalā in the Hindu calendar.
In the Brāhmaṇas, muhūrta denotes a division of time: 1/30 of a day, or a period of 48 minutes. An alternative meaning of "moment" is also common in the Brāhmanạs. In the Rigveda muhūrta exclusively means, "moment".
Each muhūrta is further divided into 30 kalā. Each kalā is further divided into 30 kāṣṭhā.
