Calendars not synchronizing in iCloud

Hey there!

I’d first check out this article:

If your iCloud Contacts, Calendars or Reminders won’t sync:

https://support.apple.com/en-us/HT203521

Otherwise, can you be more specific?

Such as how they are not syncing to iCloud?

What devices are not syncing?

How many devices are not syncing?

If they are syncing to one device, but not another? Or of none of them sync at all?

Do you sync Calendars with any other accounts other than iCloud?

If this issue started happening after any event in particular, (Such as an account change, software update/change, environment change)? Or if it’s always been this way?

Happy to lend a hand just let us know!

Appreciate any input.
