Post order data

Hello, I would ask if anyone knows a way to change the display order of the posts included in my blog. It ‘a portal to events so I included many items and thanks to a plugin (RS EVENT multiday) I can give him at least a sidebar in chronological order that respects the dates of events and not the date of insertion. Can be done also for the posts displayed on the homepage and archives of category? That is, first to always show the one with the date closest to the current date and so on?
