September spans the later part of Avani and the beginning of Purattasi, a sacred month primarily dedicated to the worship of Lord Vishnu. Purattasi is considered highly auspicious for Vishnu devotees, especially in Vaishnavite traditions. Devotees observe Purattasi Saturdays, offering prayers, fasting, and visiting temples to seek blessings. Many people avoid non-vegetarian food and perform special Vishnu Sahasranama parayanam (chanting of a thousand names of Vishnu) during this month. The belief is that Lord Venkateswara descended to Earth during Purattasi, making it a spiritually significant time for darshan at temples like Tirupati Balaji.
Astrologically, Purattasi is a month of strong Saturn influences, and hence, prayers to Vishnu are believed to mitigate Shani dosha (Saturn afflictions) in one’s horoscope. It is not generally considered an ideal month for weddings or major life events, but perfect for penance, cleansing karma, and devotion. The Shukla Paksha Ekadashi during this month is especially important for fasting and spiritual activities, drawing thousands to temples across Tamil Nadu.
Purattasi Saturdays are the most revered days of the month. Devotees flock to Vishnu temples dressed in traditional attire, with forehead tilak and sacred chants filling the air. Special poojas, offerings, and archanas are performed, and in many homes, families observe fasts and prepare prasadam for Lord Vishnu. These rituals are believed to help remove obstacles and grant prosperity and peace of mind.
While Navaratri typically begins in late September or early October, the Purattasi month is considered a spiritual prelude to this grand festival. Devotees begin preparations, clean their homes, and start planning Golu (doll arrangements) and ritual observances for Navaratri. Astrologers may recommend this time for spiritual sadhana and home cleansing activities to harmonize energies before entering the powerful month of Aippasi.
A Tamil monthly calendar typically includes important astrological details such as the Panchangam (lunar and solar calendar), which provides information about the Tithi (lunar day), Nakshatra (star), Rahu Kalam, Yamagandam, and Auspicious Timings (Muhurtham). It also lists festivals, religious observances, and special days like Ekadashi, Pournami, and Amavasya. The calendar may display details about planetary positions, and horoscopes for the month. Additionally, it includes key agricultural dates and local cultural events. Tamil calendars also highlight lunar months like Chithirai, Aadi, and Thai, providing a spiritual connection to Tamil traditions.
