Simple Blogger hack to change the post date and time manually so you can move around the post to any month as you wish. Yes you should not make your blog messy by moving posts around like a time machine as readers will find it hard to follow your blog. But it would be quite handy to bring post that you have created draft few days ago to the current date when you are publishing.
You might have already noticed the Post Option link next to the Labels for this post. click on that link and it will open up couple of options for your post and one option is the post date and time. Change it to the date and time you want, publish it and your post will be moved back or front.
