But now that you've made the distinction between `'2012'` and `'2012-12-31'` this totally makes sense:

```python
In [24]: arr.sel(time='2012')
Out[24]:
<xarray.DataArray (time: 1, age: 4)>
array([[ 0.244146,  0.702819,  0.06614 ,  0.211758]])
Coordinates:
  * age      (age) object 'age0' 'age1' 'age2' 'age3'
  * time     (time) datetime64[ns] 2012-12-31

In [25]: arr.sel(time='2012-12-31')
Out[25]:
<xarray.DataArray (age: 4)>
array([ 0.244146,  0.702819,  0.06614 ,  0.211758])
Coordinates:
  * age      (age) object 'age0' 'age1' 'age2' 'age3'
    time     datetime64[ns] 2012-12-31

In [26]: arr.sel(time=np.datetime64('2012-12-31'))
Out[26]:
<xarray.DataArray (age: 4)>
array([ 0.244146,  0.702819,  0.06614 ,  0.211758])
Coordinates:
  * age      (age) object 'age0' 'age1' 'age2' 'age3'
    time     datetime64[ns] 2012-12-31
