The date shortcode will return a formatted date. You can specify the date using an English string that is in the same format as PHP's strtotime function. For example, {date:now} will display the current date. The format of the outputted date can be specified by passing a format as a keyarg. The format used must match the format used in the PHP's date function, for example {date:now@format='Y-m-d'}.

For a full list of supported formats refer to the PHP date reference page.

If you are getting the date dynamically for example from a meta field, you may need the date for the day before it, our a few hours later. You can do this simply by specifying it in the second argument to the shortcode:

the last day for registrations is {date:{acf:start_date} '-1 day'}

You can also specify more than one interval by separating them with a command:

{date:{acf:start_date} '-1 day, -1 hour'}

If you want more precision or use dynamic values, you can do it with the timedelta shortcode, with the sub and add keyargs:

The timedelta accepted keyargs are: weeks, days, hours, minutes and seconds.

You can compare dates using the comparison shortcodes, for all dates that needs to be compared you should use a format that can be ordered, for example U. Example.

On any day before ACF start_date the message in the second line will be displayed.
