# 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"
}
]
}
}
}
}
```
{% include copy-curl.html %}
#### Example response
```json
...
"aggregations" : {
"number_of_bytes" : {
"buckets" : [
{
"key" : "03-2021-03-2021",
"from" : 1.6145568E12,
"from_as_string" : "03-2021",
"to" : 1.615451329043E12,
"to_as_string" : "03-2021",
"doc_count" : 0
}
]
}
}
}
```
