Hindu calendar, the panchang is vital in the lives of Hindus calculating dates of festivals, auspicious times & for performing rituals. It was initially based on the movement of the moon found in the Rig Veda, 2nd millennium B.C. In the first few centuries A.D., Babylonian & Greek astronomical ideas reformed the Indian calendar. Since then both solar and lunar movements were considered in calculating dates. Religious festivals & auspicious dates are still decided on the lunar movements.
Brahmā addressed Lord Kṛṣṇa as Acyuta because the Lord is never forgetful of a little service rendered by His devotee. He is so kind and affectionate towards His devotees that a little service by them is accepted by Him as a great deal. Brahmā has certainly rendered much service to the Lord. As the supreme personality in charge of this particular universe, he is, without a doubt, a faithful servant of Kṛṣṇa; therefore he could appease Kṛṣṇa.
