 Simplifying the multi-index:
 
 ```{python}
-from pandas import to_datetime
-
 df["symbol"] = df.index.get_level_values(0)
-df["date"] = to_datetime(df.index.get_level_values(1)).date

 df.reset_index(drop=True, inplace=True)

+Optionally converting dates to be datetime-aware:
+
+```{python}
+from pandas import to_datetime
+
+# fix date values (see: https://github.com/dpguthrie/yahooquery/issues/210)
+df["date"] = df["date"].astype("str")
+df["date"] = df["date"].str.split(" ").str[0]
+# convert to datetime-aware values:
+df["date"] = to_datetime(df["date"]).dt.date
+
 df[["date", "symbol", "adjclose"]].head()
