October transitions from Purattasi into Aippasi, one of the most festival rich months in the Tamil calendar. It begins with the grand celebrations of Navaratri, a nine night festival honoring Goddess Durga in her various forms. Tamil households set up Golu (decorative arrangements of dolls), perform daily poojas, recite Devi Mahatmya, and invite women and children to partake in the rituals. The final day, Vijayadashami, marks victory over ignorance and evil and is a popular day to start learning, especially for children (Vidyarambham).
Following Navaratri, the most anticipated festival is Deepavali (Diwali), which usually falls in late Aippasi or early Karthigai. Aippasi is also marked by Annabhishekam, a grand ritual where Shiva Lingams are bathed in cooked rice, symbolizing abundance and devotion. In astrology, the planetary transitions during Aippasi are vital—Venus, Sun, and Mercury play key roles in identifying auspicious days. The month is also marked by spiritual cleansing, ancestral offerings, and ritualistic prayers.
Navaratri, celebrated with music, dance, and devotion, is one of the most vibrant festivals in October. In Tamil Nadu, it is deeply connected to Goddess worship, and families install Golu steps adorned with mythological dolls and divine figurines. Sundal (savory legumes) is prepared as offering each day, and women exchange gifts, bangles, and turmeric kumkum as part of social bonding and spiritual upliftment.
Later in the month, Deepavali, the festival of lights, takes center stage. Celebrated with firecrackers, oil baths, sweets, and prayers to Goddess Lakshmi, Diwali is a major cultural and religious festival across Tamil Nadu. Astrologers consider Amavasya (New Moon) and Lakshmi Puja timings crucial, and people choose specific muhurthams for lighting lamps and wearing new clothes. The spiritual energy during this time is ideal for invoking wealth, health, and victory over darkness.
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.
