Siblings Day Foundation is a public non-profit charity devoted to establishing Siblings Day for the benefit of our families, our communities and our nation. Siblings Day has been so well accepted over the last decade that it was granted a "Service Mark" in 2007 by the U.S. Patent and Trademark Office. Our goal is to make this a federally recognized day, like Mother's and Father's Days. We need your continued support by celebrating Siblings Day on April 10th. You can celebrate by sending your siblings a card, gift, or phone call; making a dinner invitation; performing a good deed, favor, errand or chore; and in cases of deceased siblings, consciously holding them in our memory.
