What is National Siblings Day?

Also referred to as Sibling Day, the annual observance falls on April 10 and is meant to honor one's siblings.

It was founded in 1995 by Claudia Evart as a way to honor and celebrate siblings. According to the National Day Calendar, Evart had lost two siblings early in life in separate accidents. Evart created the Siblings Day Foundation and chose April 10 as the day of observance in honor of her sister, Lisette's birthday.

If you're an only child, fret not: Only Child Day is April 12, just a few days after National Siblings Day. There are also separate Brothers Day and Sisters Day in May and August, respectively.
