National Sisters Day 2025: All You Need to Know
Affiliate Disclosure
Hey fellow impactful ninja ?
You may have noticed that Impactful Ninja is all about providing helpful information to make a positive impact on the world and society. And that we love to link back to where we found all the information for each of our posts.
Most of these links are informational-based for you to check out their primary sources with one click.
But some of these links are so-called "affiliate links" to products that we recommend.
Why do we add these product links?
First and foremost, because we believe that they add value to you. For example, when we wrote a post about the environmental impact of long showers, we came across an EPA recommendation to use WaterSense showerheads. So we linked to where you can find them. Or, for many of our posts, we also link to our favorite books on that topic so that you can get a much more holistic overview than one single blog post could provide.
And when there is an affiliate program for these products, we sign up for it. For example, as Amazon Associates, we earn from qualifying purchases.
What do these affiliate links mean for you?
First, and most importantly, we still only recommend products that we believe add value for you.
When you buy something through one of our affiliate links, we may earn a small commission - but at no additional costs to you.
And when you buy something through a link that is not an affiliate link, we won’t receive any commission but we’ll still be happy to have helped you.
What do these affiliate links mean for us?
When we find products that we believe add value to you and the seller has an affiliate program, we sign up for it.
When you buy something through one of our affiliate links, we may earn a small commission (at no extra costs to you).
And at this point in time, all money is reinvested in sharing the most helpful content with you. This includes all operating costs for running this site and the content creation itself.
What does this mean for me personally?
You may have noticed by the way Impactful Ninja is operated that money is not the driving factor behind it. It is a passion project of mine and I love to share helpful information with you to make a positive impact on the world and society. However, it's a project in that I invest a lot of time and also quite some money.
Eventually, my dream is to one day turn this passion project into my full-time job and provide even more helpful information. But that's still a long time to go.
Stay impactful,
From the Brontës, to Venus and Serena Williams, to Beyonce and Solange, all of these powerful women are tied together by the special bond of sisterhood. Sisters may bicker like there’s no tomorrow, but they also can be fiercely protective and loving of their siblings.

The Most Important Information About National Sisters Day at a Glance
1️⃣ The big picture: National Sisters Day is celebrated on the first Sunday of August. This year, the holiday will fall on August 4. Since then, it has gone on to be enjoyed by people around the world. With the rise of social media, many people uplift their sisters using the hashtag #nationalsistersday, which has racked up over a hundred thousand posts on Instagram alone.
2️⃣ Why it is important: Sisterhood isn’t as widely celebrated as the love we have for parents on days like Mothers Day and Fathers Day. Therefore, uplifting our sisters can be a way to create memories and bring positivity into each other’s lives. As well as this, National Sisters Day can be another time to consider the girls across the globe who face gender-based discrimination and violence.
3️⃣ How you can get involved: You can get involved in this awareness event by reaching out to your sister—whether biological or soul sister—and enjoying a special day with her. You could watch a movie about sisters. From Frozen, to Pride and Prejudice, to Little Women, or The Parent Trap, choose your favorite! As well as this, you could write letters to one another about how much your sister means to you. Furthermore, to uplift the sisters of the world, you could donate to, or volunteer with a charity that aims to end gender-discrimination.
