Aug4 Fun Holiday – Sisters' Day

The first Sunday of August every year is celebrated around the world as Sisters’ Day.

Celebrate your sister or someone you share a sisterly bond with today.


The unofficial holiday honors the strong bond that people share with their sister(s). Sometimes called National Sisters' Day in the United States, the holiday encourages people to celebrate the special relationship between them and their sister(s).

This is a day to acknowledge the joy and love that your sister brings into your life and to make sure that she knows that you cherish all that she does for you.

Describes Many Different Relationships

While sister is usually used to refer to a female sibling, the term can be used for a variety of relationships. In many cultures, the term is used to address a female nurse, a woman who is in religious service, like a nun, or any other unrelated woman who shares a person's religion. Members of a sorority - a female social organization on college campuses - also call each other sisters.

How to Celebrate?

  • If you live far from your sister, call them or send them a card telling them how much you love them and appreciate them.
  • If you live close to them, visit them or take them out for a nice meal and treat them to their favorite dessert.
  • Don't have a sister who you share genes with? What about celebrating your female friends who have provided you the love and support that only a sister can?
