The Fourier order determines how quickly the seasonality can change (Default order for yearly seasonality is 10, for weekly seasonality order is 3).

What is Fourier order in prophet?
The inputs to this function are a name, the period of the seasonality in days, and the Fourier order for the seasonality. For reference, by default Prophet uses a Fourier order of 3 for weekly seasonality and 10 for yearly seasonality.
What is Fourier series and its applications?
Fourier series are the ones which are used in applied mathematics, and especially in the field of physics and electronics, to express periodic functions such as those that comprise communications signal waveforms.
What do you mean by Fourier series?
A Fourier series is an expansion of a periodic function. in terms of an infinite sum of sines and cosines. Fourier series make use of the orthogonality relationships of the sine and cosine functions.
What are Regressors in prophet?
Summary: Additional regressors feature is very important for accurate forecast calculation in Prophet. It helps to tune how the forecast is constructed and make prediction process more transparent. Regressor must be a variable which was known in the past and known (or separately forecasted for the future).
