Apple Calendar not syncing with Google Calendar

This worked!

From iPhone: Go to Google Calendar > Select your profile (the coloured circle with your initial in the upper right corner) > Manage accounts on this device > iCloud will appear in the list (noted as a 'system account') > make sure the toggle in ON

I tried this on both my Mac and my iPad, but when I go to "Privacy and security>Calendars" all that I see is a message saying that "Apps that have requested access to your calendar events will appear here". There is no option to select Google Calendar or designate Full Access. And just to note, I have designated Google under the Accounts setting and turned on Calendar access there.

Privacy and security>Calendars>Google Calendar>Full Access

in the Google calandar if you check your accounts there is a place to add the iCloud account and it fixed my calandar !

I am having the same problem since the OS update so frustrating and need a solution.. it was fine till I did the iOS update 17. My shared family apple calandar is showing up in the Google calandar

For me the issue was a changed google password.

Go to iOS Settings -> Calendar -> Accounts -> Gmail, check if there's an error there with a prompt to re-login. After login with the new password iOS -> Google Calendar sync works immediately, Google Calendar -> iOS takes up to 10 mins.

Thank you for trying to help. I found Full Access under privacy and security, and that was already on. I don't see a toggle for full access by going directly to Google calendar as you suggest here. What I find is Settings>Calendar>Accounts> There I find iCloud, the EXCHANGE, and the GMAIL accounts. The toggles under those categories are mail, contacts, calendars, and notes, and all those are on. Perhaps I don't understand your instructions? My iphone and google calendar were flawlessly in sync until I recently got a new iphone, and now - as the original poster explained - I can get my google calendar events on the new iphone, but any calendar event I enter on the iphone is not shared to the google calendar. I guess maybe I'll just keep messing with it until I can work past the glitch.

I just updated to iOS 16.7.1. I am wondering if this is what has caused the two calendars, iPhone and Google, to no longer sync. Also, when I search for keywords on the iCalendar, it can't find the entries. If I go to the exact date, the entries are there exactly as I remembered.

This worked for me ... to solve problem iCal (phone) not syncing To Google Cal (but other way works)

1. Create event in Apple cal … in the Event Details the option Calendar needs to be set to my - gmail address.
2. 5 secs later it appears in Google Cal PC - problem solved ... but now need to ...
3. Set the default Calendar to this, ie gmail address.
4. On phone Apple iPhone > settings > calendar > default Calendar - set to my gmail.com address
5. Solved !

still won't work. Hot Schedules used to sync with my Apple Calendar and it keeps telling me to go to the settings you recommended and nothing works. This just started when I did the ios 17 update

This is a very unsatisfying answer...but just wait 15-20min and then check your Google Calendar again (in browser and/or in iPhone app). In past years the situation used to be much worse (calendar events added to a Google Calendar via a Mac/iPhone app never showing up in Google Calendar app/browser)...but for me it commonly now just takes awhile.

Leaving the Calendar app open on Mac/iPhone (where the added event can be seen just fine) might help...or maybe that's just superstition, and waiting is all we need to do. Which implies a periodic but non-immediate server update/push, somewhere between Apple and Google, not a software bug.

Thank you so much for this - I've spent hours trying to figure this out, and your suggestion is the only thing that worked for me. I changed the settings in my Apple calendar to only show events that had been categorized under "iCloud -> Calendar" and then individually had to change those to my Gmail account. It was tedious, but at least it worked when none of the other suggestions did.

Exporting of calendars events that are created in iPhone is not possible ( so they will not sync with gmail account in the same device ) , events created from Mac Add, modify or delete events in Calendar on Mac - Apple Support can be exported Import or export calendars on Mac - Apple Support in finder > downloads and then in the same Mac , sign in with gmail address and its password and import that event in gmail account https://support.google.com/calendar/answer/37118?hl=en&co=GENIE.Platform%3DDesktop#zippy=%2Cexport-from-another-calendar-application

Note : syncing of events created in Mac to iPhone will be possible in web mail account , when gmail account is added in Mac system internet accounts ( with gmail address and password with all gmail account credentials ) .
