Bharatiya Jyotihshastra (History of Indian Astronomy), translated by R. V. Vaidya v2.c13.s2.11

v2.c13.s2.11

These muhūrtas have intimate association with every day affairs of life and it will be seen from the discussion at several places in Part I that it has continued to exist from times immemorial. In the present times marriages cannot be performed at all without muhūrtas. Ceremonies like the foundation of the house, entering a newly built house for the first time, sowing the corn and reaping the harvest, etc. cannot generally be undertaken without muhūrtas, and there are many people who undertake many such affairs of practical life only after consulting the muhūrtas. It is not the followers of Vedic religion alone, who are guided by muhūrtas; even the Liṅgāyats and Jains cannot get on for a moment without the muhūrtas. Even the Parsees and the Mohamedans seek the guidance of muhūrtas. The need of muhūrtas has been one of the main causes for developing what little knowledge of astronomy had been acquired by our people and for keeping it alive till to-day.
