National Sisters' Day is celebrated on the first Sunday of August every year. The day is observed to celebrate the unique bond between sisters. There might be days when sisters would want to strangle each other, but they always have each other's back no matter what.

Sisters' Day is an unofficial holiday that honours the strong bond that people share with their sisters. The holiday encourages people to glorify the special bond they have with their sisters. It is also a day to acknowledge the joy and love that your sister brings into your life and make sure that she knows you cherish everything she has done for you.
Interestingly, in India, a similar festival called Rakshabandhan is celebrated by Hindus. It is also around the same time as sister's day. The festival actually falls twice and year on a full moon day and honours the sacred bond between brothers and sisters. The sister ties a sacred thread around her brother's wrist while the brother gifts his sister gifts and promises to protect her for a lifetime.
The origin of sisters day is unknown but we can trace the English word for sister back to the Old Norse word 'systir', which derives from the Proto-Germanic word 'schwester'. In some societies, the term sister has broadened its colloquial meaning to include women who share a close bond. The relationship can be formed by blood or friendship. The day is also honoured to remember some sisters who have created history like the Trung sisters- Trung Trac and Trung Nhi, The Grimke sisters- Angelina and Sarah, The Bronte sisters- Charlotte, Emily and Patricia, Minerva & Antonia Mirabal.
