National Siblings Day: Date, History, and How to Celebrate

When National Siblings Day is, who started it, and simple ways to mark it.

National Siblings Day is observed every year on April 10 in the United States, celebrating the bond between brothers and sisters. It is an unofficial observance, meaning it is not a federal holiday, but it has grown popular as a day to honor and reconnect with siblings, especially through posts and photos on social media.

When it is celebrated

The date is fixed on April 10 each year rather than tied to a particular weekday. That consistency makes it easy to remember and plan around, whether you want to send a message, make a call, or meet up in person.

History and origin

National Siblings Day was founded in 1995 by Claudia Evart, a native New Yorker. She created the observance after the loss of her siblings, and she established the Siblings Day Foundation to promote it. Evart chose April 10 because it was the birthday of her late sister, Lisette. The foundation went on to gain non-profit status, and the day has since spread well beyond the United States, with recognition in a number of other countries.

Why it matters

The observance is meant to encourage people to appreciate their siblings and the lifelong relationships they share. For many, it is a prompt to reach out, express gratitude, or reflect on shared memories. Because it grew from a personal story of loss and love, the day also carries a note of remembrance for those whose siblings have passed away.

Ways to celebrate

  • Call, text, or visit your brothers and sisters.
  • Share old photos or favorite memories together.
  • Give a small, thoughtful gift or handwritten note.
  • Plan a shared meal or an activity you both enjoy.
  • Reflect on and honor siblings who have passed away.
