Tihar is a 5-day Hindu festival celebrated in Nepal and parts of India. The first day honors crows, with people leaving food offerings on their rooftops. The second day honors dogs as loyal companions. On the third day, cows are worshipped as symbols of wealth and prosperity and the goddess Lakshmi, and homes are cleaned. The fourth day involves worshipping oxen for their hard work and constructing cow dung hills. The fifth and final day is Bhai Tika, when sisters place colorful tikas on their brothers' foreheads for long life and visit temples without siblings.
