For some, this holiday-bifurcated week has posed a challenge: Just when did last weekend end and when does the new weekend begin? Set all that calendar-induced confusion aside, because here's some recommendations of things do in Westport over the next couple of days ... regardless of what your personal weekend-o-meter says:

Get new insights into one of the world's best-known love stories when a Yale professor dissects Shakespeare's "Romeo and Juliet" in a wide-ranging discussion at 2 p.m. Sunday in the Westport Public Library, 20 Jesup Road. Mark Schenker, associate dean at Yale College, will lead the program examining "a range of tensions in the play: between tragedy and comedy, parents and children, passion and responsibility, moral action and fate," the library promises, as well as discussing the play in the context of Shakespeare's era and contemporary times.

Be picky about how you end the weekend by checking out banjo virtuoso Cythnia Sayer, who performs with her Sparks Fly band at 7 p.m. Sunday at the Levitt Pavilion for the Performing Arts, 40 Jesup Road. Sayer, according to Levitt publicity, is "regarded as one of the top 4-string banjoists in the world today." The show, like nearly every Levitt event, is free.
