My darling sister and I celebrate Sisters' Day on September 17 each year. We picked that date because it was a little distant from other family celebrations, though a few years ago another anniversary emerged the week before. It's turned out to be particularly nice to celebrate our appreciation of each other so soon after the other, sadder day. This year sister sent me this, and I love it! It's made by Michelle from Canberra, Australia, and you can get your own from her Etsy store.
