Every Tuesday is considered to be a day related to Vaasthu. Vaasthu is a science of building any home or building with a balanced energy. People who want to remove any ill effects related to land, shop or building should worship Lord subramanya during sevvai hora on tuesday's by offering sevvarali garlands which are personally decorated by the worshipper himself.One should offer red coloured food items for the poor on tuesdays. This type of pooja will provide the way for owning a new house.
