Dear Colleagues, since I received this question already several times: We expect that the scientific program ends Friday (late) afternoon. We added this information on our webpage (http://ct2015.web.ua.pt/) "The scientific programme of CT2015 starts on Monday morning and ends on Friday afternoon. We are planning a welcome reception on Sunday evening." See you soon Dirk [For admin and other information see: http://www.mta.ca/~cat-dist/ ]
