classification model - problem with date column
I trained a model on an example set which includes a column date (DD.MM.YYYY) e.g. June 2020.
However the model cant be applied to another data set [with date e.g. July 2020] with exactly the same Features as in the data set to build the model. Theres always a an error which says : "mismatch of date".
Is it possible that the model cant be applied because of differen dates in the data set?
