A seven day clock includes an open-face and a single hand rotatably mounted to, and generally centrally disposed on, the face. A motor driver rotates the hand at a uniform rate of rotation, about an axis of rotation, in a plane parallel to the face. The hand rotates in complete 360 degree revolutions about the face once every seven complete days. The face is demarked into seven contiguous equal sectors each bounded by two radii extending radially outwardly from the axis of rotation and labelled consecutively with the consecutive days of a week. The clock is adapted for a user to apply removable writing so that the writing overlays the face, and so that the removable writing is within the sectors.
