Today is the day we celebrate the achievements of all women, great and small, as well as reflecting on how far some women have still to go in order to have equal rights.
There's lots of things going on in Nottingham, including this event at Nottingham Women's Centre.
In addition, there are other events over the next week all around the city. Details of these can be found here.
We hope you can find something of interest and, if not, at spend at least part of the day thinking about women worldwide.
