book:release_date

Learn how to use the book:release_date meta tag to improve your site.

Specifies the release date of the book. This meta tag is used by social media platforms to display rich information about books, including their release date.

Code Examples

<meta property="book:release_date" content="2023-07-04" />
Specifies the book release date in ISO 8601 format without timezone, assuming default timezone or when it is not critical.
<meta property="book:release_date" content="2023-07-04T00:00:00-04:00" />
Specifies the book release date and time with timezone offset, ideal for global releases where timing is critical.
<meta property="book:release_date" content="July 4, 2023" />
Using a non-ISO 8601 date format could lead to inconsistencies and incorrect display on platforms.
<meta property="book:release_date" content="07/04/2023" />
Date formats that are region-specific may cause confusion or incorrect parsing by social media platforms.

Recommendations

  • Use ISO 8601 Format
    For maximum compatibility and precision, always specify the release date in ISO 8601 format (YYYY-MM-DD).
  • Include Timezone
    If relevant, include the timezone offset with the date to specify the exact release time globally, e.g., YYYY-MM-DDThh:mm:ss+00:00 for UTC.
