Open Graph metadata
article:expiration_time
Sets the date and time after which an article is out of date. Open Graph defines the value as an ISO 8601 datetime.
Code examples
Good example
<meta property="article:expiration_time" content="2027-12-31T23:59:59Z">Sets the expiry to a precise UTC instant.
Avoid this example
<meta property="article:expiration_time" content="12/31/2027 11:59 PM">This format is region-dependent and has no timezone.
Recommendations
- 01Use ISO 8601 FormatInclude a timezone or UTC marker so consumers interpret the same instant.
- 02Use It for Real ExpiryAdd this property only when the article has a known expiry. Most evergreen articles do not need it.
