As an airline pilot, I live by the time a lot. I check my calendar to see what is on it multiple times a day, hoping that I can have a long stretch of days off.

Losing all of the events on my calendar would make me feel like I don’t know what I am going to be doing throughout the next couple of weeks which makes it hard for me to be organized.

In this article, we’re going to take a look at how to restore accidentally deleted calendar events on iPhone and get them back should we lose them.

Why May Calendar Appointments Disappear From My iPhone?

There are a couple of reasons why you may have lost calendar events that have already been on your iPhone.

  • 👥 Account Issues: If you share your calendar with someone else, such as a spouse or a business, then someone else could be deleting your calendar events and remove them from your iPhone.
  • 🔁 Syncing issues: If you’re using Google as your method of syncing your calendar events on your iPhone and then changing it to iCloud, sometimes changing where you sync through can delete the calendar events off of your iPhone.
  • 📊 Corrupt iPhone Data: If the storage on our iPhone is failing, it could be possible that events can disappear even after we’ve created them and put them onto our device.

No matter what the reason, there are ways for us to restore calendar events on iPhone.

Knowing how to restore calendar events should we lose them enables us to have more control over our data. Simply knowing how to recover them gives us the peace of mind that we know what to do should we lose them.

In addition to knowing what to do should we lose them, it’s important to also work on prevention. I would recommend that you use iCloud to prevent data loss as you receive a free amount of storage and it’s an amazing service as no one thinks that calendars will be deleted from their iPhone.


The best way to find deleted calendar events would be to download and use Disk Drill. This is the first method that we want to use because there is no Recently Deleted Folder for Calendar events like there is for Photos on our iPhone.

  1. Download and install Disk Drill onto your Mac.
  2. Plug your iPhone into your Mac and then select the device from under iPhone & iPad.
  3. Wait for the scan process to complete.
  4. Review the files that Disk Drill was able to recover and then click on the blue Recover button to restore them back onto your Mac.

I would use iCloud for this as once you turn it on, you don’t even have to think about it anymore. By default, iCloud calendar sync should be on. You can check and make sure that it’s turned on by grabbing your iPhone and checking your settings.

  1. Unlock your iPhone and go to Settings.
  2. Click on your name at the top of Settings.
  3. Navigate to iCloud.
  4. Check and make sure that the Calendars are turned on.

If you want to start your calendar over, this can be done. Simply follow the steps below to reset your iPhone calendar.

  1. Grab your iPhone and launch the Calendar app.
  2. Click on Calendars at the bottom of the screen.
  3. Next to the Calendar that you want to delete, click on the red  “i” icon.
  4. Then click on Delete Calendar.
