Fix Error: To ensure parsing is consistent and as-expected, please specify a format

I got this error in python:

To ensure parsing is consistent and as-expected, please specify a format.
idx=pd.to_datetime(mydata.index)

Here’s how to fix it:

# Example format: 'YYYY-MM-DD'
idx = pd.to_datetime(mydata.index, format='%Y-%m-%d')

If you’re using another Date format like 7/5/22, then use:

date = pd.to_datetime(mydata.index, format='%m/%d/%y')

Just to clarify:

%Y represents year 2022 (4 digits)

%y represents year 22 (2 digits)
