python pandas extract unique dates from time series

Question

I have a DataFrame which contains a lot of intraday data, the DataFrame has several days of data, dates are not continuous.

 2012-10-08 07:12:22            0.0          


        

Answer 1

Just to give an alternative answer to @DSM, look at this other answer from @Psidom

It would be something like:

pd.to_datetime(df['DateTime']).dt.date.unique()

It seems to me that it performs slightly better
