How do I get day to show on every post?

Since I recently switched themes, I don’t have the date showing on every post like in my old theme. I was wondering how I could add this in? Which php file I might have to edit, or what line of code i will have to put somewhere? My site is at : https://www.windsorcitywatch.com

Any help would be greatly appreciated. Since my posts are news related, I really need the date to be with them. The time is already there, but no date. Only the first post shows the date.
