Date Format

In your settingspanel under tab ‘formats’.

That works for global site-wide changes, but it doesn’t seem to effect Events Manager’s formats.

I dont know what you mean. If you want changes in your template you can use e.g.

<div id="event-time">																			

<p><?php echo $EM_Event->output('#_{l, j F, Y}'); ?></p>
																</div>

I think bettercallsaul meant Events > Settings > Formatting > Date/Time – have you tried that?

Sorry, didn’t even notice the tabs across the top. Yes, you can change the date/time order for Events Manager in those tabs.
Thank you.
