### Window by calendar months and years
InfluxQL does not support windowing data by calendar months and years due to their varied lengths.
Flux supports calendar month and year duration units (`1mo`, `1y`) and lets you
window and aggregate data by calendar month and year.
```js
from(bucket:"telegraf/autogen")
|> range(start:-1y)
|> filter(fn: (r) => r._measurement == "mem" and r._field == "used_percent" )
|> aggregateWindow(every: 1mo, fn: mean)
```

### Work with geo-temporal data
InfluxQL doesn't provide functionality for working with geo-temporal data.
The [Flux Geo package](/{{< latest "influxdb" "v2" >}}/reference/flux/stdlib/experimental/geo/) is a collection of functions that
let you shape, filter, and group geo-temporal data.
```js
import "experimental/geo"
from(bucket: "geo/autogen")
|> range(start: -1w)
|> filter(fn: (r) => r._measurement == "taxi")
|> geo.shapeData(latField: "latitude", lonField: "longitude", level: 20)
|> geo.filterRows(
region: {lat: 40.69335938, lon: -73.30078125, radius: 20.0},
strict: true
)
|> geo.asTracks(groupBy: ["fare-id"])
