March 3rd is a day known as Girls' Day in Hawaii, or Hinamatsuri in Japan. Culturally, I can't tell you much about it, but we celebrated it in Hawaii when I was growing up. Mainly that entailed having the boys put up all the girls' chairs at the end of the school day. Now that's something from the hanabata days.
Nowadays I don't do anything at all to celebrate Girls' Day except for make some sort of status update on Facebook. Some years I have been known to call up my mom and lament the fact that she didn't send me a Girls' Day present. This year I did no such thing as I am just being grateful.
