 ## Using date math with index rollovers
 
-When using an index alias for time-series data, you can leverage [date math](https://opensearch.org/docs/latest/field-types/supported-field-types/date/) in the index name to track the rollover date. For example, you can create an alias pointing to `my-index-{now/d}-000001`. If you create an alias on June 11, 2029, then the index name would be `my-index-2029.06.11-000001`. For a rollover on June 12, 2029, the new index would be named `my-index-2029.06.12-000002`. See [Roll over an index alias with a write index](#rolling-over-an-index-alias-with-a-write-index) for a practical example.
