It is a weight-driven clock (the weight chain is removed) with a verge escapement (K,L), with the 1 second pendulum (X) suspended on a cord (V). The large metal plate (T) in front of the pendulum cord is the first illustration of Huygens' 'cycloidal cheeks', an attempt to improve accuracy by forcing the pendulum to follow a cycloidal path ...
It can also be formulated as the instantaneous rate of change of the number of rotations, N, with respect to time, t: n=dN/dt (as per International System of Quantities). [4] Similar to ordinary period, the reciprocal of rotational frequency is the rotation period or period of rotation, T=ν −1 =n −1, with dimension of time (SI unit seconds).
The period T is the time taken to complete one cycle of an oscillation or rotation. The frequency and the period are related by the equation [4] =. The term temporal frequency is used to emphasise that the frequency is characterised by the number of occurrences of a repeating event per unit time.
The seconds pendulum, a pendulum with a period of two seconds so each swing takes one second. The seconds pendulum, a pendulum with a period of two seconds so each swing takes one second, was widely used to measure gravity, because its period could be easily measured by comparing it to precision regulator clocks, which all had seconds pendulums ...

Everyone’s cycle looks different, so there could be a number of reasons behind why your period came early. A typical menstrual cycle is thought to last exactly 28 days—however, it can actually ...
