How do I find my posts on my timeline from a year ago on facebook?

[Paul]

You can try to find the post from your activity log. You can also try to find it from your timeline, for that, you have to go to the year, and then the month, and the click 'show more posts' to see all the post of that month.

If non of these above works, try to do it in a different way. Go to the friends timeline where you saw the post, find the post, and as the post is yours, i think you will be able to edit or delete it form your friends timeline as well. You will also see that just below the post, the date of the post is showing. If you click on that, the hyperlink will take you to your original post. You can delete it from there.
