1. Unable to add or disappearing events on iPhone Calendar

Users have reported problems with saving events for dates in the past; many have observed that the events with a past date only show up in their calendar for a few seconds and then they are gone. The most likely reason for this problem is that your iPhone Calendar is getting synchronized with iCloud or another online calendar service and also that your iPhone is set to sync only the recent most events. To change it, go to Settings > Mail > Contacts >Calendars; here you should be able to see '1 month' as the default setting. You can click on this option to change it to 2 weeks, 1 month, 3 months or 6 months or you can also select All Events for syncing everything in your calendar.

2. Calendar showing incorrect date and time

In case your iPhone Calendar is showing wrong date and time, follow these steps carefully and one after the other to rectify the issue.

Step 1: Make sure that you have the most up to date version of iOS on your iPhone. The easiest way of doing this is to update your iPhone wirelessly over the air. Plug in your iPhone to a power source, go to Settings > General > Software Update and then click on Download and Install and then when the popup window appears, select Install to begin the installation.

Step 2: Check if you have the option available for enabling date and time to be updated automatically; go to Settings > General > Date & Time and turn on the option.

Step 3: Make sure that you have the correct time zone set up on your iPhone; go to Settings > General > Date & Time > Time Zone.

3. Calendar information lost

The best way to ensure that you do not lose all your Calendar data is to archive or make copies of your Calendar from iCloud. To do this go to iCloud.com and log in with your Apple ID, then open the Calendar and share it publicly. Now, copy the URL of this shared calendar and open it in any of your browsers (please note that instead of 'http' in the URL, you have to use 'webcal' before pressing the Enter / Return button). This will download and ICS file on to your computer. Add this Calendar file to any of the calendar clients that you have on your computer, for example: Outlook for Windows and Calendar for Mac. Once you have done this, you have successfully downloaded a copy of your Calendar from iCloud. Now, go back to iCloud.com and stop sharing the calendar.

4. Duplicate calendars

Before resolving the issue of duplicate calendars on your iPhone, log into iCloud.com and see if the calendar is duplicated there as well. If yes, then you have to contact the iCloud Support for more help.

If not, then start by refreshing your calendar on iPhone. Run the app Calendar and click on the tab Calendar. This should show the list of all your calendars. Now, pull down on this list to refresh. If refreshing doesn't resolve the issue of duplicate calendars then check if you have both iTunes and iCloud set to sync your calendar. If yes, then turn off the sync option on iTunes as with both the options on, calendar may get duplicated, so leaving just iCloud set up to sync your calendar, you should see no more duplicate calendars on your iPhone.

5. Unable to see, add or download attachments to a calendar event

Step 1:Ensure that the attachments are supported; following is a list of file types that can be attached to a calendar.

  • Pages, Keynote, and Numbers documents. The documents created using Keynote version 6.2, Pages version 5.2 and Numbers 3.2 need to be compressed before being attached.
  • Microsoft Office documents (Office '97 and newer)
  • Rich Text Format (RTF) documents
  • PDF files
  • Images
  • Text (.txt) files
  • Comma-separated value (CSV) files
  • Compressed (ZIP) files4
  • Step 2: Ensure that the number and size of attachments is within 20 files and not more than 20 MB.

    Step 3: Try refreshing the Calendar

    Step 4: If all the steps above still do not resolve this issue, quit and reopen the Calendar app once.
