The templating system in WordPress is very flexible, and there's rarely something you can't do or that doesn't work as you'd expect. A notable exception however is the_date. Its purpose is simple enough. It displays the current post's date of creation. But on pages with more than one post (such as on many blog home pages), something weird happens. If a number of posts on any given page were created on the same date, the_date will only show that date for the first of those posts.
In the early days of blogging, posts were usually listed by date, much like a regular, paper diary. In the old default theme that comes with WordPress a big date title is used to separate posts into days. That's what the_date was created to do, and so it makes sense it only displays the same date once. In most modern themes however, people like the date to be among the meta data for each article, so the_date falls short.
