   Also, we should be careful to follow Pandas' logic when adding/subtracting a mixed interval:
   ```python
   >>> end = begin + pd.DateOffset(days=1, hours=24)
   >>> end - pd.DateOffset(days=1, hours=24) == begin
   True
   
   >>> end == begin + pd.DateOffset(days=1) + pd.DateOffset(hours=24)
   True
   >>> end == begin + pd.DateOffset(hours=24) + pd.DateOffset(days=1)
   False
   
   >>> end - pd.DateOffset(days=1) - pd.DateOffset(hours=24) == begin
   False
   >>> end - pd.DateOffset(hours=24) - pd.DateOffset(days=1) == begin
   True
   ```
