Saturdays of Purattasi: Like Aadi Fridays are important days for praying to Goddess, Purattasi Saturdays are very important and special prayers are done for Venkatachalapathy with people following many Vrathams and pujas with various offerings like chakara pongal etc.
Mahalaya Amavasya: The 15 days preceding the New moon day of Purattasi is considered as Mahalaya Paksham (full moon to new moon) period. During this time, our forefathers are supposed to come close to us on this earth and people generally offer special prayers to them with tharpanam, mahalaya srartham etc. This is followed not only for one’s forefathers but for all the departed kith and kin.
Navrathri : Once the rituals for the
forefathers are completed, the time for celebration begins with Navrathri (nine nights,
literally). The first day of Navrathri is
the day after the Mahalaya Amavasya completes
and continues for ten days. The first three days pujas are for Goddess
Parvathi, the next three days for Goddess Lakshmi and the last three days for
Goddess Saraswathi - the third day of puja to Goddess Saraswathi (the ninth of
the celebrations) being celebrated as Saraswathi Puja in households and Ayudha Puja in workplace. The tenth day is Vijaya
Dasami meaning the victorious tenth day when the Goddess slew Mahishasuran.
