Darsha Amavasya – It is a highly significant Amavasya in the Hindu Calendar. While Amavasya in general marks the no moon day, Darsha Amavasya refers to the night when the moon is completely absent. Moon god is invoked though one cannot see the moon in the sky. Offering prayers and doing Shradh sacraments is considered highly auspicious.  As evil forces or energies are at their peak, many Tantric pujas and black magic practices are also carried on this day.

Margashirsha Amavasya – It is believed that fasting on Margashirsha Amavasya cleanses the devotees’ lives of all faults and gives peace and wealth. The Hindu scriptures state that this month of Margshirsha is solely devoted to Lord Krishna. People are required to bathe in the Ganga, Yamuna, and other sacred rivers during this holy month. Devotees participate in religious rituals such as Kirtans and Bhajans, which are thought to be very fortunate. Other names for this month include Magsar and Agahan.

The Anvadhan and Ishti are the most auspicious days for the natives of Vaishnava Sampradaya. Ishti in colloquial term means desire. Ishti refers to the act of doing a deed and invoking a deity to obtain something. In Sanskrit Anvadhan means the ritual of adding fuel to keep the sacred fire burning after performing the Agnihotra (a havan or a homam). Ishti is celebrated on the full Moon day or Purnima of every month, based on the Hindu Lunar calendar. It is also recommend to observe a fast on Ishti and perform Japa of Vishnu mantras in meditation or to perform Satyanarayan Katha.  On Anvadhan auspicious day, the natives belonging to the Vaishnava Sampradaya or devotees of Lord Vishnu as a ritual keep a day-long fast. The Anvadhan and Ishti are the most auspicious days for the natives of this Vaishnava Sampradaya. They celebrate the Purnima (full moon) and Amavasya (new moon) as the two sacred days of the month. The Yajnas conducted for Anvadhan and Ishti is that these do not last for two or more days, like any other religious Yajnas. Both the Anvadhan and Ishti, Yajnas are conducted only for 1 whole day and this makes it simple for the devotees to come and watch it or even take participation in it in the first place.
