He appeared in court and spoke only to confirm his name, giving an alias of Adam Mendes.
He was remanded in custody and is due to face a hearing at Nottingham Crown Court on 20 June.
The victims include 19-year-old University of Nottingham students Barnaby Webber and Grace O'Malley-Kumar, as well as 65-year-old school caretaker Ian Coates.
All three died from knife injuries.
Calocane is also accused of using a van to drive at three pedestrians, who were injured but are now stable.
Calocane is a former University of Nottingham student, but it is not clear if his former student status is linked to the inquiry.
The case has caused an outpouring of grief in Nottingham and beyond.
