# Date range aggregations
|
||
|
|
|
||
|
|
The `date_range` aggregation is conceptually the same as the `range` aggregation, except that it lets you perform date math.
|
||
|
|
For example, you can get all documents from the last 10 days. To make the date more readable, include the format with a `format` parameter:
|
||
|
|
|
||
|
|
```json
|
||
|
|
GET opensearch_dashboards_sample_data_logs/_search
|
||
|
|
{
|
||
|
|
"size": 0,
|
||
|
|
"aggs": {
|
||
|
|
"number_of_bytes": {
|
||
|
|
"date_range": {
|
||
|
|
"field": "@timestamp",
|
||
|
|
"format": "MM-yyyy",
|
||
|
|
"ranges": [
|
||
|
|
{
|
||
|
|
"from": "now-10d/d",
|
||
|
|
"to": "now"
|
||
|
|
}
|
||
|
|
]
|
||
|
|
}
|
||
|
|
}
|
||
|
|
}
|
||
|
|
}
|
||
|
|
```
|
||
|
