| 04 | Broadcast date | Date when a TV or radio program was / will be broadcast |

| 15 | Until date | Date until which a content item or supporting resource may be referenced or used |
| 17 | Last updated | Date when a resource was last changed or updated |
| 24 | From… until date | Combines From date and Until date to define a period (both dates are inclusive). Use for example with dateformat 06 |
| 27 | Available from | Date from which a supporting resource is available for download. Note that this date also implies that it can be immediately displayed to the intended audience, unless a From date (code 14) is also supplied and is later than the Available from date |
| 28 | Available until | Date until which a supporting resource is available for download. Note that this date does not imply it must be removed from display to the intended audience on this date – for this, use Until date (code 15) |

| 32 | Associated end date | End date referenced by the supporting resource, for example, the ‘latest exam date’ for an official recommendation |
