Happy National Siblings Day! Siblings Day Foundation founder Claudia Evart was inspired to create a recognized day to celebrate and honor siblings after losing her own siblings early on in life. She chose April 10 specifically, as it is the birthday of her late sister.

Evart’s goal is to create a nationally known holiday, similar to Mother’s and Father’s day. Do something nice for your sibling today to let them know how much you appreciate them.

Because today is National Siblings Day, we’d like to remind you of our Siblingship DNA Test. If you want to know if siblings share one or both biological parents in common, a Siblingship DNA Test can determine the statistical probability of whether they are half or full siblings, or unrelated.
