Siblings Day is a holiday recognized annually in some parts of the United States and Canada on April 10, and as Brothers and Sisters Day on May 31 in Europe. Unlike Mother's Day and Father's Day, it is not federally recognized in the United States, though the Siblings Day Foundation is working to change this. Since 1998, the governors of 49 states have officially issued proclamations to recognize Siblings Day in their state. Siblings Days are celebrated also in India. The Hindu holiday of Raksha Bandhan, which is the oldest festival in this category, also celebrates the bond of brothers and sisters.
