Add, Share, and Sync Calendars on Mac & iPhone - Guide

Optimizing Calendar Usage on Mac and iPhone
Effectively leveraging the Calendar application on your Mac or iPhone is crucial for maintaining organization. This guide will detail the processes of adding, sharing, and synchronizing calendars across your devices.
The built-in Calendar app for both Mac and iPhone provides comprehensive tools for scheduling appointments, establishing reminders, and generally managing your schedule to prevent missed engagements.
Ensuring Calendar Synchronization
For seamless calendar synchronization between your devices, it’s essential to be signed in with the identical iCloud account. This ensures consistency, mirroring the functionality of Reminders, where actions performed on your Mac are reflected on your iPhone or iPad, and vice versa.
If calendar data isn't appearing across your devices as expected, verify that you are logged into the same iCloud account. Alternatively, you may be experiencing an issue with iCloud synchronization.
Further instructions on troubleshooting synchronization problems will be provided later in this article.
Adding Calendars
You can add various types of calendars to your view. These include:
- iCloud Calendars: These are automatically synced across all your Apple devices.
- Exchange Calendars: Commonly used for work or school accounts.
- Google Calendars: Integrate your Google Calendar for unified scheduling.
- Other Calendars: Subscribe to public calendars or add calendars in iCalendar format.
To add a calendar on your Mac, open the Calendar app and select "File" > "New Calendar." On your iPhone, navigate to "Settings" > "Calendar" > "Accounts" and choose "Add Account."
Sharing Calendars
Sharing calendars allows others to view your schedule or collaborate on events. You can share individual calendars or specific events.
On your Mac, right-click the calendar you wish to share and select "Share Calendar." On your iPhone, go to "Settings" > "Calendar" > select the calendar > and choose "Share Calendar."
Troubleshooting iCloud Sync Issues
If your calendars aren't syncing, try these steps:
- Verify iCloud Status: Ensure iCloud is enabled in "System Preferences" (Mac) or "Settings" (iPhone).
- Check Internet Connection: A stable internet connection is required for synchronization.
- Restart Devices: A simple restart can often resolve temporary glitches.
- Sign Out and Back In: Sign out of your iCloud account and then sign back in.
Regularly checking these settings will help maintain a consistently synchronized calendar experience across all your Apple devices.
Creating and Sharing New Calendars
A new calendar can be created by navigating to the "File" menu, selecting "New Calendar," and subsequently choosing "iCloud."
The newly created calendar will then be visible within the iCloud list located in the left-hand pane of the Calendar application.
You have the ability to assign any desired name to the calendar. Sharing options are accessible by clicking the share icon positioned to the right of the calendar’s name.
It is even possible to designate the calendar as a public one, allowing anyone to subscribe to a read-only view of its contents.
Your new calendar will become accessible on both your iPhone and iPad. Launch the Calendar app and tap the "Calendars" link found at the application’s bottom.
All of your iCloud calendars, including the one you just created, will now be displayed. Shared calendars will indicate who is sharing or with whom they are being shared.
Calendar editing can be initiated by tapping the "i" symbol adjacent to a calendar, or by selecting the "Edit" button and then choosing the specific calendar you wish to modify.
Within the edit screen, you can rename or delete the calendar. More importantly, you can manage sharing permissions and add individuals with whom you want to share it.
Scroll down to customize the calendar's color or to set it as publicly accessible.
It’s important to remember that making a calendar public allows anyone to subscribe to a read-only version. Therefore, avoid including any sensitive personal information or events.
Calendar editing also serves as the method for adding them. Just as on your Mac, a new calendar created on your iPhone will synchronize and appear on any other devices linked to the same iCloud account.Ensuring Proper Synchronization
Successful synchronization indicates everything is functioning correctly. If newly created calendars aren't visible across your devices, verifying connection to the identical iCloud account is crucial.
Should this not resolve the issue, a review of your iCloud settings is necessary to confirm calendar synchronization is activated.
On your iPhone or iPad, navigate to the Settings application and then select "iCloud".

Within your iCloud settings, locate and ensure that "Calendars" is enabled.

Subsequently, on your Mac, access System Preferences and then select "iCloud". Similar to the process on your iOS device, review the settings and confirm a checkmark appears beside Calendars.

This outlines the process for adding, sharing, and synchronizing calendars on both your Mac and iOS devices. The functionality mirrors that of Reminders, allowing calendar sharing with others and synchronization across all iCloud-connected devices.
A key benefit of connected calendars is the elimination of redundant effort, such as recreating calendars and events. Furthermore, sharing calendars ensures all parties remain informed.
