After Calendar sync., every event shows every day. Not a new problem and don't recall when it first happened but a couple of years ago. I tried in again vain to sync the other day, first time since first occurrence, and now my phone is also screwed.

Synchronising Calendar between iPhone and MacBook. It's not one event. It's every event. For example, every recurring birthday is now showing up every day. Every day is everyone's birthday.
This is obviously a long standing system problem because as I wrote, it first occurred a couple of years ago and I stopped syncing. I've changed phone and MBP since that first time and mistakenly figured Apple might have sorted it out. Alas not. I'll have to wipe each device's Calendar files and back up again. What a pain.
What exactly do you mean by "calendar sync?" Have you tried deleting the event and re-adding it?
Calendar sync results in every event showing every day
