Ghatasthapana is one of the significant rituals during Navratri. It marks the beginning of nine days festivity. Our scriptures have well defined rules and guidelines to perform Ghatasthapana during a certain period of time at the beginning of Navratri. Ghatasthapana is invocation of Goddess Shakti and doing it wrong time, as our scriptures forewarn, might bring wrath of the Goddess Shakti. Ghatasthapana is prohibited during Amavasya and night time. The most auspicious or Shubh time to do Ghatasthapana is first one third of the day while Pratipada is prevailing. If due to some reasons this time is not available then Ghatasthapana can be done during Abhijit Muhurta. It is advised to avoid Nakshatra Chitra and Vaidhriti Yoga during Ghatasthapana but those are not prohibited. The most important factor to consider is that Ghatasthapana is done before Hindu midday while Pratipada is prevailing.
