Hi Sofia. Thanks for your question. We’re limited in helping with customizations, per our Scope of Support / Terms. However, I can try to help point you in the right direction.
I’m guessing you’ll want to make good use of our Themer’s Guide (via a child theme).
If any specific hangups come along, feel free to specify what code you’re using, what the issue is (e.g. what function to use to pull in the Event Start Time), and a screenshot mockup or video screen capture demonstrating what you’re trying to accomplish.
If implementing your own customizations isn’t an option for you at this time (limited ability or time), please reference our list of known customizers.
Thanks!
