Simple upcoming

This is another simple plugin to add a little functionality of a
calendar to your blog. With this plugin you can specify, for any of
your posts, an associated “Event Date” using a new widget in the post
editor. Then, elsewhere on your site, you can retrieve a list of
future events using the [upcoming] shortcode on any post or page.

The shortcode supports several options:

• category_name: If defined, show posts only from these
  categories. You can provide multiple comma-separated category
  identifiers (slugs).

• days_old: Show events whose Event Date is no more than this many
  days past. The default is 0, which shows only events taking place
  today or later. If you enter a non-numeric value such as infinity,
  then all matching events will be shown regardless of the Event Date.
