The Date All Day project adds 'All Day' functionality to date fields, including an 'All Day' theme and 'All Day' checkboxes for the Date select and Date popup widgets.
This latest release (1.x-2.2.1) adds the possibility of customising the suffix
added to 'All Day' fields through additional configuration settings for the date
field. These suffixes are now also given the class date-display-suffix.
Additionally, this module serves as an example of how other modules can inject new functionality into date fields using various hooks provided by Date and by the Field API.
This module is a port to Backdrop of one part of the Drupal project 'Date'.
Install this module using the official Backdrop CMS instructions at https://backdropcms.org/guide/modules.
No configuration is needed.
