Organize Calendar List on iPhone

If you're like me, you've googled "How do I arrange my iCloud calendars on my iPhone?" or "How do I reorganize my iCloud calendars?" or some other variation but couldn't find anything but suggestions for 3rd party apps & forum posts that are decades old.

I finally figured it out and I hope that this save you some effort.

1) Simply login to your iCloud account on a computer & go to your calendar.

2) Don't open any settings. Just have your regular calendar list visible.

3) Click & Drag your calendars up & down into the order you want them to appear.

They immediately took on the same order on my phone after I logged out. I didn't even have to refresh my calendar on my phone.

IF you need to refresh it, open your calendar list on your iPhone upon completion and then drag the list downwards with your finger. That'll make a loading bar appear & that means its refreshing the list.
