Vaisakha Masam is considered as one of the most sacred months among the Hindu Lunar Months. According to Skandha Puraana; Krutha Yuga among the ages; Holy river Ganga (Ganges) water among the Theerthas; Jala Daana (donating water) among charities; and Vaisaakha maasam among the months are said to be the best.
It is the sacred month in which three of Lord Vishnu’s incarnations’ viz. Parashuraama (sukla Thrutheeya); Naarasimha (sukla Chaturdasi) and Kuurma (sukla Pournami) avatharas have taken place. Vaisaakha Sukla Trutheeya is celebrated as Akshaya Thrutheeya one of the most auspicious days in Hindu calendar. According to sacred scripts it is said to be the day Tretha Yuga had commenced reckoned as Tretha Yugaadi. According Simhachala Kshethra Mahatmya, Vaisaakha maasam is the sacred month Lord Vishnu manifested in dual form (Varaaha + Naarasimha) at Simhachala Kshethra during Krutha Yuga.
Among the incarnations of Lord Vishnu; Naarasimha avathara has attained a rare significance and unique importance. All His avatharas are generally in a single form. But Nrusimha avathara is that of a dual form; Nara + Simha. According to sacred scripts, Naarasimha-avathara occurred in Krutha Yuga during Vaisaakha maasam on the lunar day of sukla Chaturdasi in the constellation of Swathi during Pradosha time. To commemorate incarnation of Lord Naarasimha, special celebrations are held every year on this day called Nrusimha Jayanthi.
Vaisaakha maasam is the sacred month Lord Venkateswara (Sreenivaasa) married Goddess Padmavathi Devi on the auspicious day of Vaisaakha sukla Dasami according to Bhavishyottara Puraana.

At the famous temple of Sri Satyanarayana Swamy at Annavaram in Andhra Pradesh; Kalyaanotsavam celebrations are held on the sacred day of Vaisaakha Sukla Ekaadasi. Electional astrology considers Vaisaakha maasam as one of the most auspicious months for performing auspicious ceremonies like marriage; upanayanam; gruha pravesa etc.
