Yes, my mistake. I originally wrote that, but then managed to confuse myself and immediately edited the comment to what it is now. Too late to change it now.
Sorry to be a pedant - it's 118 years since the "original" 1904 Bloomsday but it's the 119th Bloomsday, if you include the first one. (1905 was one year after the original but was the second Bloomsday etc).
There are events all over Dublin today to celebrate [1].
