My iPad calendar is not showing all of my calendars, only birthdays. How do I see all calendars

Well, i found this POST that help me a LOT: https://discussions.apple.com/thread/5545469

My problem was that i have not the last versión of iOS, so I installed, the iPad inicialize and after a moment my calendar shows everything.

THis is what worked for me in my iPad.

Settings>Mail, contacts, calendars>Calendars>Sync>All Events is selected.

And of course making sure those calendars are selected in the pulldown.

I had to go to settings and change sync to all events from one month. set it on the correct default calendar while I was in there as well. Not sure how both got hosed up but that was what hid all my calendar entries that I thought had vanished.

I was having the same problem, including notes and reminders. I went through the steps in Deactiva's link. That didn't work. Then I went to Settings>Mail, contacts, calendars>Fetch New Data>Fetch and then selected Hourly (it was Manually). Then everything started showing up.

I had the same problem. My iPhone calendar was fine but my iPad only had Birthday calendar.

I noticed in Settings that my Default Calendar had reverted to "Calendar" instead of my gmail calendar. I reset the Default Calendar to my gmail calendar..

Settings > Mail, Calendar, Contacts > scroll to Calendar section and click Default Calendar.

Once I did that, all my calendar content returned from both my gmail and my Exchange calendars.

I found my home, work and personal calendars ONLY after creating my Google account for calendars as an iCloud type of account. IAW, you may sign in with Gmail address, but it is an AppleID for a iCloud account that is only associated with a Gmail address.

HTH 🙂

Try opening the calendar app. At the bottom is word "Calendars", probably in red. Open this. Then pull down on this screen and let it refresh. This should restore all calendars. Hope this works for you. It did for me.

This works! Thanks a lot.
