Sororities all over the world are participating in International Badge Day Monday in a celebration of sisterhood.

Established in 1997 by the National Panhellenic Conference, the day is generally recognized today during National Women's History Month.

This year's theme and logo, "Wear Your Letters on Your Heart," was created by a student at Spring Hill College in Alabama.

The creation of the event reaches back to spring 1996 when Nora M. Ten Broeck wrote an article titled: "A Simple Solution – Wear Your Membership Badge Today."  The past three years, the theme has been "Keep Your Fraternal Experience Close to Your Heart."  The NPC said that the theme often changes with the input of volunteers and members.

The NPC has invited the National Pan-Hellenic Counci, the National Multicultural Greek Council, the National Asisan Pacific Islander American Panhellenic Association and the National Association of Latino Fraternal Organizations to participate.

University of Minnesota sororities are wearing pins around campus today to show their support, said Angela Ugorets, Panhellenic Council president.  She said that chapters wear pins, usually decorated in gold and silver with symbols unique to their sorority, on Monday nights druing meetings but today is an opportunity to show the entire campus.  Many chapters have also been active with social media updates on Facebook and Twitter.

Ugorets also said that a proposal has been made to have greek letter days on Fridays, further promoting greek chapter awareness.
