Saving a post as draft for later publishing in Blogger is very easy to do. This is not the same as scheduling. When you save the post for later, it means that the post just isn't finished at this time and you will continue to work on it at a later time. You can see this as a draft for your future post.

To do this, just click on the "Save" on your top right and your post will be saved.
