The auspicious timing, or shubh muhurat, for tying the Rakhi on Raksha Bandhan holds significant importance in Hindu tradition. This specific time is chosen based on the alignment of celestial bodies, particularly the position of the Moon. It is believed that performing the Rakhi tying ceremony during an auspicious muhurat enhances the bond between siblings, bringing good fortune, protection, and positive energy. The absence of bhadra (inauspicious time) is crucial, as it is considered unfavorable for such rituals.
