Reading (ie., trying to read) Pushkin's Eugene Onegin in Russian, with help from a couple translations (including Nabokov's).
Learned that Pushkin began writing it in Kishinev in the 1820s, on a May 28th. A very important date in the longy-long poem Stubborn Grew/The Rose - for one thing, the poem was finished on May 28th. (Stubborn's story begins with a Halloween search for a lost cat named Pushkin, and the 3rd main vol. (July) peters out with allusions to Pushkin's story The Queen of Spades.)
