Within the Ayyavazhi tradition, the rhythm of the year is marked by several major observances that center on Ayya Vaikundar and the sacred text *Akilattirattu Ammanai*. Foremost among these is **Ayya Vaikunda Avataram**, regarded as the most important festival, commemorating the divine incarnation of Vaikundar. This is observed on the twentieth day of the Tamil month of Masi, and is especially prominent at Swamithoppe Pathi and other principal *pathis*. The celebration gathers devotees in large numbers for special worship, processions, and communal practices that highlight the movement’s emphasis on dharma and unity.

Another key observance is **Thiru–Edu–Vasippu**, a long, scripture-centered festival devoted to the continuous recitation of *Akilattirattu Ammanai*. This is held annually, lasting for an extended period in the Tamil month of Karthigai, and is conducted in a central manner at Swamithoppe as well as, on a smaller scale, in various *nizhal thangals*. Through this sustained reading, the community ritually re-enters the sacred narrative, allowing the text to shape collective memory and ethical orientation. The festival thus becomes not merely a ritual duty, but a shared contemplative journey through the foundational revelations of the tradition.

Equally significant are the **Kodiyettru Thirunal** or **Kodiyettru Vizha** celebrations, ten-day flag-hoisting festivals conducted at Swamithoppe Pathi and other important centers. These involve the ceremonial raising of a religious flag, daily rituals, processions, and religious discourses, often accompanied by communal feasts. The act of hoisting the flag functions as a visible sign of spiritual sovereignty and communal solidarity, drawing together diverse devotees under a single emblem of faith. In this way, the festival weaves together devotion, doctrine, and social cohesion.

Beyond these major events, the tradition also observes commemorations of significant moments in Vaikundar’s life and the history of the Five Main Pathis, as well as gatherings that honor early disciples and followers. Weekly assemblies, especially on certain days, and occasions of *anna dhanam* (food distribution) further extend the festival spirit into regular communal practice. Through collective worship, scriptural recitation, shared meals, and remembrance of sacred history, these observances embody the Ayyavazhi vision of a community shaped by righteousness, equality, and spiritual unity.
