I\'ve taken my Series and coerced it to a datetime column of dtype=datetime64[ns] (though only need day resolution...not sure how to change).

I think for solving that problem, you can use this code, it converts date type to int types:
df['date'] = df['date'].astype(int)
df['date'] = pd.to_datetime(df['date'], unit='s')
for getting date only, you can add this code:
pd.DatetimeIndex(df.date).normalize()
df['date'] = pd.DatetimeIndex(df.date).normalize()
