Introduction most of the pendulum clocks work under the influence of gravity. The length of the pendulum and gravity are the two parameters that control the time of oscillation. It is given by the famous equation (1), discussed later in this paper. If the length is varied, then the time period also changes. The length variation is normally due to temperature variation. But if the gravitational force varies then also the time will vary. But an effort has been done to compensate the length variation in proportion to the variation of gravity. This paper gives theoretical design of a pendulum clock which is independent of the variation of gravity, even though it operates due to gravity itself.
