April 13 is the birthday of two of my favorite writers: Samuel Beckett and Seamus Heaney. Both are Irish and Nobel laureates and geniuses.
(The most recent Nobel laureate J. M. G. Le Clézio was also born on this day: I haven't read him yet. But one can already find the beginning of Ukrainian translation by Roman Horbyk of his Poisson d'or here: http://translitera.org/2009/ле-клезіо-золота-рибка-1/#more-1508.)
So, happy days!
