Brāhma Muhūrta is a Sanskrit term, which is composed of two words Brāhma and Muhūrta. Brāhma Muhūrta is the Time of Brāhman. Brāhma means Sacred or Creator Divine, and Muhūrta means Auspicious Time. Brāhma Muhūrta is the 14th Muhūrta Kāla of the night. One Muhūrta is a period of 48 minutes, the whole night consisting of 15 Muhūrtas. Brāhma Muhūrta is an auspicious Time or period of 48 minutes that begins 1 hour 36 minutes before sunrise and ends 48 minutes before Sunrise. .When we consider the night as the period from the evening sunset to the next day morning sunrise, then the last quarter of the night is the Brāhma Muhūrta time. That is anywhere between 3:30 a.m. to 5:30 or 6:00 a.m. Some Countries the Sunrise and Sunset may vary. Based on the geographical location of your place, Brāhma Muhūrta depends on whatever is the time of sunrise. According to the Bharat - Indian Traditional way, the Great Sages, Rishi’s (ṛṣi’s) said Brāhma Muhūrta is the best and  the most ideal time to wake up from bed in the morning, for starting our day in a sacred way with practices like Meditation, Prāṇāyāma, Prayers etc.
