Remembering to post every day, and which days you already posted, is super easy with this plugin. 
It shows you a calendar with days red when there isn’t a post, and days green when there is. Green 
days you can hover over and see the title of the post, and click to edit the post for that day.

wpFutureCal

A simple calendar that displays when you edit posts, showing which days you have posted on.

<h4>不是已经有类似的插件了吗？比如 WP Missed Schedule</h4>
如果你发布文章后还有后续动作，比如同步文章到微博，发邮件通知等等，在网站并发时（同一时间很多人挤进来），这个时候触发了wp-missed-schedule等插件会导致同步多条微博或者多封邮件。
MY Missed Schedule 插件用了定时的原理，这种方式不会导致多次触发。这也是我做这个插件的原因，因为wp-missed-schedule无法跟 <a href="https://wptao.com/wp-connect.html" rel="nofollow ugc">WordPress连接微博</a> 的“同步微博”功能完美组合使用。如果你也碰到类似问题，一起来试试 MY Missed Schedule
