The day is considered auspicious for prayers and new beginnings. Although major ceremonies are traditionally limited during the Tamil month of Aadi, many families consider Aadi Perukku a favourable occasion to begin new ventures, initiate discussions for auspicious events, and pray for prosperity and family well-being.

For married women, the festival also holds special significance, as many traditionally change their Thali Kayiru, or sacred Mangalsutra thread, and offer prayers for a happy married life and their husband`s well-being and longevity.

In 2026, Aadi Perukku falls on Monday, August 3.

Aadi Perukku is celebrated annually on Aadi 18. In 2026, the festival falls on a day associated with Panchami Tithi and Uthirattathi (Uttara Bhadrapada) Nakshatra, adding to its traditional significance.

As Aadi Perukku falls on a Monday in 2026, devotees may also offer special prayers to Lord Shiva and Bhairava.

Why is Aadi Perukku Celebrated?

Aadi Perukku reflects the close relationship between Tamil culture, agriculture and water resources. The festival falls during the monsoon season, when rivers and other water bodies traditionally receive increased inflows.

People offer prayers for abundant rainfall, sufficient water resources, agricultural prosperity and family well-being. The festival is especially significant along the Cauvery River, where families gather on the riverbanks to worship and express gratitude to the river.

Similar to the way the Sun is honoured during Thai Pongal, rivers and water sources are worshipped during Aadi Perukku for their vital role in agriculture and daily life.

Aadi Perukku Traditions and Rituals

On Aadi Perukku, devotees traditionally visit rivers, lakes and other water bodies and offer fruits, sweets, grains and different varieties of rice as part of their prayers.

Married women perform special prayers for marital well-being and traditionally replace the sacred yellow thread of their Thali. It is believed that observing this tradition brings Mangalyam strength, prosperity and marital happiness.

Unmarried women may tie a turmeric-dyed yellow thread while praying for a suitable life partner and a happy married life. Newly married couples may also perform special rituals and prayers seeking prosperity, harmony and happiness in t their new life together.
