About Sandhi Puja:
Sandhi Pooja is a very significant ritual during Navratri Pooja. It is performed at the point when Ashtami Tithi ends and Navami Tithi begins. This is believed to be the moment when Devi Chamunda appeared to kill the demons Chanda and Munda.
Sandhi Pooja is dominant for two Ghatis or approximately lasts for 48 minutes. It is possible that Sandhi Pooja Muhurta occurs at any time of the day and Sandhi Pooja should be done during that time only.
