Prophet: How to exclude weekends ( saturday & Sundays) from fb Prophet

[obaidM]

Hello FB Prophet community,

I am getting outrageous predictions on Saturday and Sunday.Mainly because they shouldn't be there.
How can I remove weekends from the daily data to begin with.

So that my input data never has a weekend and my predictions never have a weekend.

The model won't have any issues if you remove the weekend days prior to passing in the data, and you'll just want to be sure that the dataframe of future dates that you pass into predict also has weekend days stripped out. It's pretty easy to identify weekend days in a dataframe and just drop them; here is how you would do it in pandas, and similar commands exist in R:

df_no_weekdays = df[df['ds'].dt.dayofweek < 5]

Run that command on the history before passing it into fit, and on the future dates before passing it into predict.
