National Siblings Day, according to our sources, was created by Claudia Evart in 1995, and the non-profit The Siblings Day Foundation is soon to follow in 1997.

Claudia Evart was inspired to create this beautiful holiday of National Siblings Day in honor of her own siblings, who passed away far too soon. Her brother Alan, who sadly passed at the age of 36, and her sister Lisette, who also unfortunately passed away at the age of 19. Claudia Evart created National Siblings Day to honor her relationship and love for her siblings and to encourage others to hold their siblings close, make memories together, and be there for one another.

National Siblings Day is celebrated on April 10th, Claudia Evart’s sister Lisette’s Birthday.
