Any Data Tag that has a date value, such as [created], [publish_up], [modified], or even custom fields of type calendar, can be output and have the date format specified.

[publish_up format="F jS Y"]

September 26th 2021

The date format characters that you can use are based on the PHP date function.

You can also use date values inside If Structures, like:

{if created >= '2019-02-15'}...{/if}

And you can even compare dates to the current date using Relative Dates or the now() value.

{if publish_up > now()}Coming soon{/if}
