How do I convert timestamp to datetime.date in pandas dataframe?

Question

I need to merge 2 pandas dataframes together on dates, but they currently have different date types. 1 is timestamp (imported from excel) and the other is datetime.dat

Answer 1

I found the following to be the most effective, when I ran into a similar issue. For instance, with the dataframe df with a series of timestmaps in column ts.

df.ts.apply(lambda x: pd.datetime.fromtimestamp(x).date())

This makes the conversion, you can leave out the .date() suffix for datetimes. Then to alter the column on the dataframe. Like so...

df.loc[:, 'ts'] = df.ts.apply(lambda x: pd.datetime.fromtimestamp(x).date())
