iPhone 13 Pro 18.3.2 won't sync with iMac Sequoia 15.3.2

Entered dates on either device but won't sync with each other. Tried rebooting both devices, checked settings with no luck. My entered dates were disappearing on my iPhone 13 Pro. Both devices have current IOS. Any suggestions? Is this a glitch with Apple?

If you're trying to use the same calendar on all your Apple devices, surely the best way to accomplish that is to use iCloud calendar. This explains how to set that up.

Entering an event on any date only to have it either disappear (iPhone) or never sync with either device whether it's entered on my iPhone or my iMac. I'm using the calendar that comes with the Mac IOS. They're not communicating with each other. This happened after the last IOS update. On previous entered events, you can see the "circling arrows" in the top right of the event but any new events entered, there are no arrows which would indicate to me they aren't syncing with each other.
