Shayani Ekadashi (Sanskrit: शयनी एकादशी, romanized: Śayanī Ekādaśī, lit. 'eleventh day of sleep'), also known by various other names, is the eleventh lunar day (Ekadashi) of the bright fortnight (Shukla Paksha) of the Hindu month of Ashadha (June - July). This occasion is holy to Vaishnavas, the followers of the Hindu preserver deity, Vishnu, as it is regarded to be the day the deity's sleep commences.
