Change start and end time

Hi,

Is this for a front-end form for user-submitted events?

Hello!
Yes, it is, so users just see the opening hours
So

at the moment you need to code for this and you can change this using custom jquery and template at events-manager/templates/forms/event/when.php

to use templates: https://wp-events-plugin.com/documentation/using-template-files/

Hello, thank you for your answer.
Could you just be more specific as i am really new at this!
Do you have any example of code I can use?

Many thanks for your help!

So

you can try this jquery timepicker demo – https://jonthornton.github.io/jquery-timepicker/
