June 16th is BLOOMSDAY, the day in 1904 on which all the action of James Joyce’s novel Ulysses takes place. It is celebrated every year on 16th June by Joyceans all over the world.
In Dublin, where the novel is set, Bloomsday celebrations go on for a week with most of the attention on the day itself 16th June. It is traditional to dress up and go out for the day, visiting the locations of the book and taking part in readings, walks and activities of all sorts which in some way connect with Ulysses, its author and its world.
