Kalashtami or Kala Ashtami is a Hindu festival dedicated to Lord Bhairav and is observed every Hindu lunar month on the ‘Krishna Paksha Ashtami Tithi’ (8th day during the waning phase of moon). The ‘Ashtami Tithi’ (8th day) after ‘Purnima’ (full moon) is considered to be most suitable day to propitiate Lord Kaal Bhairav. On this day, Hindu devotees worship Lord Bhairav and keep a fast to please Him. This puja helps to reduce the obstacles, barriers and hurdles and also remove sorrows, unhappiness and miseries from lives. Kalashtami is also considered holier when it falls on a Sunday or Tuesday, as these days are dedicated to Lord Bhairav.
