There is a minor gap between these two terms. Let’s understand them in a convenient way.
Cyclicity means a dominant cycle, for instance about a business firm. There is a time of the year when the sales are low. But in the end days of the quarter, suddenly there is a rise in the sales graph. This dominant period is somewhat different than seasonality which means a year.
Seasonality mainly refers to the changes that occur yearly. More like a change that is dependent on the seasons of the year. Just understand that periodicity of seasonality will be roughly 365 days. The observed pattern will tend to repeat after the completion of a year.
