Seasonality is an annual process but most cycles are not annual. In addition, cycle is something that is spread over a large span of time. For instance the trend of a particular style of jeans stays in-fashion for a couple of years and then it becomes outdated.
What is the difference between seasonality and cyclicality?
Likewise, what is the difference between seasonality and cyclicality? Seasonality is always of a fixed and known period. Hence, seasonal time series are sometimes called periodic time series. A cyclic pattern exists when data exhibit rises and falls that are not of fixed period.
What is meant by seasonality?

What are the two terms of seasonality?
Seasonality could be directly taken into consideration as the famous four climatic seasons and the subsequent changes that are important for the biotic component of the Earth. On the other hand, the main nutrient and climatic cycles have direct influences on the biotic matter. Both seasonality and cycles do have a direct relationship with sunlight as it is the main cause for all the seasons and cycles.
How many seasons are there in a year?
As a year takes place, four different climatic seasons could be experienced, especially for the temperate countries. Spring, Summer, Autumn (aka Fall), and Winter are those four seasons that take place in each year due to the famous tilt of the Earth at an angle of 23.50.
What are the cycles of life?
Cycles are anything that takes place in a recurring manner. One of the most renowned cycles would be the Earth’s cycles along its own axis and around the sun (known as days and years respectively). Based on these prolific cycles, takes place all the other cycles, which are important to sustain the life. The life on Earth has been based on Carbon, Hydrogen, and Oxygen (aka CHO); hence, the cycles of these basic elements are highly important for life on Earth. Additionally, the cycling of other nutrients (such as Nitrogen) is also important for the sustenance of the life. Reproductive cycles, fruiting cycles, menstrual cycle, life cycle, and many other biological cycles are taking place on earth; each of those has its own cycling frequency. Most of those frequencies are related to annual cycling patterns.
Why is the cycle of oxygen and carbon important?
Additionally, the cycling of other nutrients (such as Nitrogen) is also important for the sustenance of the life.
What is the most important fact about cycles?
However, one of the most important facts about cycles would be that each cycle is interrelated with most of the others.
Why does the Earth rotate around the Sun?
The Earth is a planet of the solar system and all the planets travel around the sun on a definite track due to the gravitational properties of the sun. Additionally, the Earth itself rotates around its own axis while travelling around the sun.
What would happen if one natural pattern was affected?
If one natural pattern were affected, then all the other related cycles would be disturbed; environmental pollution is one such related effect that, as a result, almost all the natural cycles being disturbed.
Why do cyclical and seasonal behavior drift over time?
Cyclical behavior on the other hand can drift over time because the time between periods isn't precise. For example, the stock market tends to cycle between periods of high and low values, but there is no set amount of time between those fluctuations. Series can show both cyclical and seasonal behavior. In the home prices example above, there is ...
What is seasonal behavior?
A seasonal behavior is very strictly regular, meaning there is a precise amount of time between the peaks and troughs of the data. For instance temperature would have a seasonal behavior. The coldest day of the year and the warmest day of the year may move (because of factors other than time than influence the data) but you will never see drift ...

This behavior shows a seasonality of almost exactly 11 years, so a yearly time series of the heat put out by the sun would have a seasonality of 11. In many cases the difference in seasonal vs cyclical behavior can be ...
Can gym attendance be seasonal?
You can also have multiple seasonal (or cyclical) effects. For example, people tend to try and make positive behavioral changes on the "1st" of something, so you see spikes in gym attendance of course on the 1st of the year, but also the first of each month and each week, so gym attendance has yearly, monthly, and weekly seasonality.
What is the difference between seasonal and cyclical?
The essential difference between the seasonal and cyclical components is that seasonal effects occur at regular, predictable intervals, whereas the timing of cyclical effects is less predictable.
What is seasonal behavior?
A seasonal behavior is very strictly regular, meaning there is a precise amount of time between the peaks and troughs of the data. For instance temperature would have a seasonal behavior. Click to see full answer.
What is seasonal time series?
