The Post Calendar plugin replaces the standard WordPress post list with a calendar view, so you can see your published and scheduled posts laid out by date.
Why You’ll Like the Post Calendar plugin
See your publishing schedule at a glance instead of scrolling a long list. Rescheduling is one click: click any post on the calendar, pick a new date and time from the popup, and you’re done.
Have unscheduled drafts? The “Drafts” button shows them all in one place so you can quickly assign each a publish date. The plugin is a good fit for bloggers, content marketers, news sites, or anyone managing an active content calendar. Settings let you choose which post types get the calendar view and whether to add a calendar link to the admin menu.
