The periodicity of elements is a phenomenon

WebbThe components of time series are trend, seasonality, periodicity and randomness. A trend is a continuous upward or downward change in a time series over a long period of time. Seasonality is also called seasonal variation, which is a periodic fluctuation of time series that recurs within a year.
