Well, are perpetual calendars and clocks the same thing? In feng shui, is the clock with hands hanging in the living room the same as the electronic perpetual calendar clock?

Well, a perpetual calendar and a clock are the same thing. In geomantic omen, clocks with hands and electronic perpetual calendars hung in the living room can be generalized, but in the sleeping bedroom, clocks are forbidden, with circles indicating rolling and clocks indicating "moving", which affects sleep. In the living room, it is a shady place where round or "moving" objects can be hung.
