Where were you last Pluterday? is a serio-comic science fiction novel by Paul van Herck, originally released in Dutch in 1968 as Sam, of de Pluterdag by J.M. Meulenhoff (in their science fiction and fantasy range M=SF as the 14th book of the range) and released in English by DAW books in 1973.
The novel won the first prize at the European Science Fiction Convention (EuroCon)[2] in Trieste, Italy.
The theme in the book is Pluterday, an extra day in the week which can be withdrawn if one saves enough time (e.g. by taking a plane instead of a train). Only the rich can save enough time and thus Pluterday is in practice reserved for the "happy few", resulting in a class society. The existence of Pluterdays is kept secret from non-privileged people.
