I am using FBProphet to predict future values in my monthly datasets.
I noted the following in the documentation.
Note that with weekly or monthly aggregated data, many holiday effects will be well-captured by the yearly seasonality, so added holidays may only be necessary for holidays that occur in different weeks throughout the time series.
Questions
For monthly data, does that mean I do not need to add holidays that fall on a fixed date? For example, Christmas day.
For Chinese New Year, it falls on either Jan or Feb each year. So do I assign 1 Jan 20XX or 1 Feb 20XX to Chinese New Year, depending on the year?
Thanks for your advice.
