When scheduling posts on your WordPress blog, a few of the right plugins can make this job easier and more manageable.
First, use the Dashboard Widget Scheduled Posts plugin. This plugin creates a widget for your WP Dashboard that lists the upcoming posts that are scheduled, but not yet published.
Second, use the Future Posts Calendar plugin. This plugin creates two sets of calendars based on your scheduled posts. One calendar resides in the right column of the New Post page that you’ll see when you’re writing a new post or editing a previous one. The second calendar will be seen by site visitors as it resides in a widget that you can choose to add to a sidebar of your blog.
When there are no scheduled posts, the future calendar on the New Post page will have the current date in bold.

When at least one post is scheduled for future publication, the future calendar – either on the New Post page or in the blog sidebar – will have differently colored backgrounds depending on the number of posts scheduled for that day.

A green background indicates one post, light blue means two posts and blue means three posts scheduled for that day.
Clicking a date in the calendar will change the scheduled posting date. Nice feature!
If you’re not bothered by editing code, you can alter the PHP file to make a dashboard widget, too.
If you want to ad a widget to your dashboard, uncomment the line
add_action('wp_dashboard_setup', 'fpc_setup_dashboard_widget');
in the future_calendar.php file.
The dashboard widget only shows the date of future posts in the calendar format, so I prefer the Dashboard Widget plugin as it includes post titles.
