Vaasakkal Vaikka Naal refers to the auspicious day to lay the doorstep stone (Vaasakkal) during the construction of a new house. In Tamil tradition, placing the Vaasakkal (threshold stone) is considered a sacred and vital part of housewarming rituals. This ceremony symbolizes protection, prosperity, and positive energy entering the new home. Before fixing the Vaasakkal, people consult Panchangam (Tamil calendar) or an astrologer to find a good muhurtham (auspicious time) that ensures harmony and growth for the family. The ritual is often performed with pooja, coconut breaking, and traditional offerings to invite divine blessings. A properly chosen Vaasakkal Naal is believed to remove negative energy and bring wealth, happiness, and peace into the household.
