By default, blogs display posts in reverse chronological order on the home page with the latest post at the top.
There isn’t a way to display posts in chronological order however you can makes some posts sticky so the post will be “stuck” to the top of the blog’s front page.
Examples of where teachers might use a sticky post are for notifying students of important dates and provide assignment information. This option should only used for one or two posts on a blog.

Once you have written your post just:
1. Click on Edit in the Visibility area of the Publish module
