for a single month
```
ds.isel(ds.time.dt.month == 1)
```

for multiple months
```
ds.isel(ds.time.dt.month.isin([1, 2, 3]))
```

using groupby's new getitem method
```
ds.groupby(""time.month"")[1]
```
I think we want to encourage the first two; since groupby does a bunch of extra work.

I think we can add an indexing subsection under ""Datetime components"" showing the first two and link to that from the section you just edited.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,978473315

I think this is clearer and potentially faster

``` python
ds.isel(time=ds.time.dt.month.isin([1]))
```

I noticed that this is not mentioned in the docs for [indexing using ``isin``](https://xarray.pydata.org/en/stable/user-guide/indexing.html#selecting-values-with-isin) so you could update that too if you're up for it.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,978473315
