About Sisters Day
Sisters Day, also known as National Sisters Day, falls on the first Sunday of August each year. In 2026, that date is Sunday, 2 August. Founded in 1996 by Tricia Eleogram of Tennessee, the day celebrates the unique bond between sisters — whether biological, adoptive, step, or chosen. It’s a chance to honour that relationship, mend any rifts, and remind the sisters in your life how much they mean to you.

Sisters Day is an annual celebration dedicated to the special relationship between sisters. The day recognises all forms of sisterhood, from biological siblings to close friends who share a sister-like bond. It encourages people to reach out, reconnect, and express gratitude for the sisters in their lives. While primarily observed in the United States, the sentiment behind the day resonates with people around the world.

How to Celebrate Sisters Day
Whether your sister lives across the road or across the globe, there are plenty of meaningful ways to celebrate:
- Plan a sisters’ day out — Book a meal, visit a spa, go for a hike, or simply spend the afternoon doing something you both enjoy. Quality time is the heart of what this day is about.
- Write a heartfelt letter — In an age of quick text messages, a handwritten letter or card carries real weight. Tell your sister what she means to you and recall a favourite shared memory.
- Create a photo album or scrapbook — Gather old photos from childhood through to the present and put together a collection that captures your journey as siblings. Digital photo books make this easy even from a distance.
- Call or video chat — If you can’t be together in person, a phone call or video call can bridge the gap. Make it more than a quick check-in — set aside proper time to catch up.
- Send a thoughtful gift — It doesn’t need to be expensive. A book she’d love, a piece of jewellery with meaning, or a hamper of her favourite treats shows you’ve been thinking of her.
- Start a new tradition — Use Sisters Day as the launch for an annual tradition, whether it’s a yearly trip together, a shared recipe you cook on the same day, or a joint charitable donation.
- Reconcile and reconnect — If there’s distance or tension in the relationship, Sisters Day can serve as the motivation to reach out and begin mending things. A simple “I’ve been thinking about you” can open the door.
History of Sisters Day
Sisters Day was founded in 1996 by Tricia Eleogram, along with her friend Stacey Berry, in Tennessee. Eleogram created the day to honour the bond of sisterhood and to encourage people to celebrate the sisters in their lives. The choice of the first Sunday in August was deliberate — placing it during summer when families are more likely to gather and spend time together.
The concept of honouring siblings is not new. National Siblings Day, celebrated on 10 April, was founded in 1995 by Claudia Evart in memory of her siblings who passed away. Sisters Day carved out its own niche by focusing specifically on the sister relationship, acknowledging its particular dynamics of closeness, rivalry, support, and shared history.
Over the decades, the day has grown well beyond its Tennessee roots. Social media has amplified its reach, with millions of posts shared each August under hashtags celebrating sisterhood. The day also extends beyond biological sisters to include step-sisters, sisters-in-law, and close friends who share a sisterly bond.
Noteworthy Facts About Sisterhood
- Research from Brigham Young University found that having a sister is linked to better mental health, with sisters encouraging communication and emotional expression within families.
- The word “sister” derives from the Old English “sweostor” and the Proto-Germanic “swestēr,” both related to the Latin “soror.”
- Famous sister duos in history include the Bronte sisters (Charlotte, Emily, and Anne), the Williams sisters (Venus and Serena), and the Kardashian-Jenner sisters.
- According to a 2014 study published in the Journal of Family Psychology, sibling relationships — particularly between sisters — tend to become closer and more supportive with age.
- The Sister Study, run by the US National Institute of Environmental Health Sciences, enrolled over 50,000 sisters of women who had breast cancer, making it one of the largest studies of its kind.
