One of the main differences between Posts and Pages is Posts are listed in reverse chronological order, based on the time published while Pages are static content. In most themes, you’ll see the date of each post – usually after the post title or right after the post excerpt. Here is an example from Twenty Twelve theme, the default theme for WordPress 3.5:
If you’re a developer and you would like to place the date or time anywhere in your theme, you could use
the_time(). For more information, please visit the WordPress Codex.
