# SCTE-35 ad marker EXT-X-DATERANGE
<a name="scte-35-ad-marker-ext-x-daterange"></a>

This section is an addendum to [SCTE-35 and SCTE-104 message processing in Elemental Live](scte-message-processing.md). Elemental Live supports the EXT-X-DATERANGE ad marker style in the manifest created for an HLS output.

To select this marker, do the following:
+ In the event, go to **Output Group** > **Apple HLS** > **Advanced** > **Ad Markers** and select **EXT-X-DATERANGE**.

The structure and contents of the line are as described in HTTP Live Streaming, draft-pantos-http-live-streaming-23 (Version 23).

This marker style applies when the SCTE-35 messages are time\$1signal or splice\$1insert, and when the messages are passed through from the input or inserted at runtime using the REST API.

**Example**  
This example shows an ad avail with an ID of 999 and a planned duration of 30 seconds. The first `EXT-X-DATERANGE`, for the start of the ad avail, includes a `START-DATE`. The second `EXT-X-DATERANGE` includes an `END-DATE` and a time that is 30.03 seconds later.

**Note**  
The `DURATION`, `PLANNED-DURATION` and `END-DATE` tags are optional. If they are not present in the input or not specified in the REST API command, then these tags are omitted from the manifest.
