Proper Converting

Fortunately, this issue can be easily fixed. The .to_datetime() method has yearfirst and dayfirst boolean parameters that define whether dates start with the year or day, respectively. By default, both parameters are set to False, which is why the first numbers were considered as months (if possible). Since the dates in our data start with the day, we just need to set the dayfirst parameter to True.

Task

Convert the 'Date' column to datetime type, considering that the day comes first.
Output the first 5 rows and dtypes of the df dataframe.
