How to show Calendar Events side-by-side instead of overlapping?

Hello dontHaveTime,

Thank you for reaching out in Apple Support Communities. You can view calendar events at the same time by opening the events in separate windows. This is the method that's available and can help you to easily view your calendar events:

Always open events in separate windows

1. In the Calendar app  on your Mac, choose Calendar > Preferences, then click Advanced.

2. Select “Open events in separate windows.”

Open an event in a separate window

1. In the Calendar app  on your Mac, double-click the event you want to open in a separate

window.

2. Place the pointer over the top edge of the window, then drag the window where you want it.

This information is outlined in the Calendar User Guide for the Mac: View events in separate windows in Calendar on Mac - Apple Support

You can also provide feedback to Apple if you're looking for a different method in viewing the calendar events. Here's the link: Product Feedback - Apple

Kind regards.
