Seasonality

Definition of Seasonality 🎉

Seasonality is a characteristic of a time series in which the data experiences regular and predictable changes that recur every calendar year. It represents any predictable fluctuation or pattern that recurs or repeats over a one-year period. This means that just as you can always count on summer BBQs, companies can always brace for the annual rush of holiday shopping (yes, Santa’s visit and financial analyst’s predictions are as reliable as the seasons!).

Seasonality vs. Cyclical Effects 🚀

Feature	Seasonality	Cyclical Effects
Periodicity	Repeats every calendar year	Can vary; may span shorter or longer than a year
Predictability	Predictable changes based on seasons	Less predictable, tied to broader economic factors
Example	Higher retail sales in Q4 due to holidays	Increased sales during economic booms

Examples of Seasonality 🏖️❄️

Retail Sales: Retail businesses typically see seasonal spikes in sales during the holiday season (fourth quarter). Be prepared for huge queues and your bank account crying!
Agricultural Production: Various crops have harvest seasons, leading to fluctuations in supply and pricing. If you ever wanted a gourmet avocado toast in winter, sorry, you’ll have to wait for spring.
Tourism: Many destinations experience seasonal influxes of tourists, with summer and holiday periods being the busiest times. Nothing screams “national park congestion” like summer vacation!

Trend: A long-term motion or movement in a direction over time. Think of it as the verse of your favorite song that never really changes!
Cyclicality: Refers to patterns that manifest due to economic fluctuations or cycles but are not confined to a specific time frame. Imagine those ups and downs trying to serenade your bank balance during a recession.
