Thoughts on how the commonly used Previous/Next or Back/Next pagination link is not a good UI practice:
Never use the phrases Previous/Next or Back/Next that cause confusion in the first place for date-based output in your web application. Instead, explicitly make your labels for pagination say Older and Newer to make it abundantly clear to users.
Makes sense, and I’m guilty of this too. Might want to consider this for your next WordPress theme!
