There are several ways  although I do believe the one you mention  and dislike  is the most readable one    gt  gt  gt  t datetime date today    gt  gt  gt  datetime datetime fromordinal t toordinal    datetime datetime 2009  12  20  0  0   gt  gt  gt  datetime datetime t year  t month  t day  datetime datetime 2009  12  20  0  0   gt  gt  gt  datetime datetime  t timetuple    -4   datetime datetime 2009  12  20  0  0    and so forth -- but basically they all hinge on appropriately extracting info from the date object and ploughing it back into the suitable ctor or classfunction for datetime

The accepted answer is correct  but I would prefer to avoid using datetime min time   because it s not obvious to me exactly what it does  If it s obvious to you  then more power to you  I also feel the same way about the timetuple method and the reliance on the ordering   In my opinion  the most readable  explicit way of doing this without relying on the reader to be very familiar with the datetime module API is   from datetime import date  datetime today   date today   today with time   datetime      year today year       month today month      day today day      That s my take on  explicit is better than implicit

Today being 2016  I think the cleanest solution is provided by pandas Timestamp   from datetime import date import pandas as pd d   date today   pd Timestamp d    Timestamp is the pandas equivalent of datetime and is interchangable with it in most cases  Check   from datetime import datetime isinstance pd Timestamp d   datetime    But in case you really want a vanilla datetime  you can still do   pd Timestamp d  to datetime     Timestamps are a lot more powerful than datetimes  amongst others when dealing with timezones  Actually  Timestamps are so powerful that it s a pity they are so poorly documented

Do I really have to manually call datetime d year  d month  d day   No  you d rather like to call date to datetime dt   which you can implement once in some utils time py in your project  from typing import Optional from datetime import date  datetime  def date to datetime      dt  date      hour  Optional int    0      minute  Optional int    0       second  Optional int    0  - gt  datetime       return datetime dt year  dt month  dt day  hour  minute  second
