Python datetime object not displaying the correct date

I'm trying to convert an UTC string to a python datetime object.

The string I want to convert is: 2016-12-16T23:00:00.000Z and it is in UTC format. When I convert code to a different timezone I get 2016-12-16 23:00:00+01:00 which is a correct behaviour.

My question is, why when I access the datetime object, the day is still 16 and not 17, as I would expect to happen when 1 hour is added to 23:00.

What am I missing?

My code 

tz = pytz.timezone("Europe/Ljubljana")
dt = datetime.datetime.strptime(start_date, "%Y-%m-%dT%H:%M:%S.000Z")
date = tz.localize(dt)

print 'Date: ', date.strftime('%d')
print 'Date: ', date

Result 

Date:  16
Date:  2016-12-16 23:00:00+01:00

This is the expected behavior. dt has no time zone set. When you call tz.localize(dt), you simply assign the timezone.

Here's what you want to do:

tz = pytz.timezone("Europe/Ljubljana")
dt = datetime.datetime.strptime(start_date, "%Y-%m-%dT%H:%M:%S.000Z")
dt = dt.replace(tzinfo=pytz.utc) # you specify the time is UTC
print dt.astimezone(tz) # and now you convert dt to your preferred timezone

You obtain:

datetime.datetime(2016, 12, 17, 0, 0, tzinfo=<DstTzInfo 'Europe/Ljubljana' CET+1:00:00 STD>)
