There is a custom post type to describe Events in your company. You can build a unique layout using the available Elementor and Custom Companion widgets.
So basically, you create an individual post describing each Event. To do that, you need to go to the Events > Add new.
While editing the Events on the backend, you can set featured image and edit Event Information:
The Event date and Event time should be set to display the Correct timer to show how much time is left before the event starts using The Event Countdown widget.
The Event speakers can be added through Dashboard > Events > Speakers.
