Can You Sync Calendars Between Two Apple Accounts?

Yes, but first choose what “sync” should mean. Two people can privately share one iCloud calendar, and you can view accessible calendars together without merging Apple Accounts. Maintaining copies between two separate calendars is a different arrangement and needs access to both accounts and a tool that can copy between them.

Share one calendar for joint planning

Create or choose an iCloud calendar, then use its sharing controls to invite the other Apple Account. Grant editing permission if both people should maintain the schedule, or viewing access if one person only needs to follow it.

The recipient accepts using the account you invited. Both people can then work with the same shared calendar while keeping their Apple Accounts separate.

Apple's calendar-sharing guide explains private invitations and editing controls.

For a family setup, see creating a shared iCloud calendar. Keep individual calendars private unless there is a clear reason to share them.

Show the shared calendar alongside your own

You can bring another person's calendar into your own account's view through the private invitation. On a tablet or computer, sign in to iCloud.com/calendar with the invited account, open the calendar inbox, and choose Join Calendar for that invitation. Apple documents these acceptance steps.

The joined calendar appears on iCloud.com and on devices signed in to that same invited account with iCloud Calendar enabled. On iPhone, open Calendar → Calendars and select the shared calendar alongside your own. You can view both without replacing the device's main Apple Account.

For an account you own separately, you can also open its calendar in a separate signed-in browser session. That provides access without changing the phone's account. Apple Calendar and iCloud Calendar are separate parts of the setup; adding account access does not transfer ownership.

Use a public feed only for a public schedule

iCloud can publish a read-only calendar link for compatible subscribers. That is useful when the schedule is appropriate for public access, but it is not the same as a private invitation to another Apple Account.

A subscription does not let the recipient edit the original, and changes arrive according to the receiving app's refresh behavior. Don't make a household calendar public just to skip setting up private sharing.

For the distinctions, read ICS files and links.

Separate copies for different audiences

Sometimes one shared calendar is not the desired outcome. You may want a detailed personal appointment in one account and only generic busy time in another calendar.

Manual copies work for occasional appointments, provided someone updates them when plans change. Automatic copying can suit a frequently changing source, but the service needs appropriate access to both calendars and clear handling of updates and cancellations.

Decide where to maintain each appointment before enabling copies. In Avum, edit the source original; a destination copy is not another place to update that original, even when you have rules in both directions.

Using authorized iCloud connections in Avum

Avum supports Apple Account connections using app-specific passwords. Connect each authorized account you intend to use and confirm the required calendars actually appear before creating a rule.

A privately shared calendar may have fewer writing rights than one you own. If it is unavailable as a destination, ask the owner for editing access where needed. A sync rule cannot grant that permission.

Use a Sync Rule for the selected source and destination, with a generic title and omitted notes where the destination only needs availability. Keep editing the appointment in its original calendar. Avum Calendar is a separate option for reviewing connected sources together.

Avum is unnecessary when native sharing already gives both people the collaborative schedule they need. It becomes relevant when a second calendar needs a separate busy block that follows later changes.

Before enabling broad copying, use one test event to inspect the destination's time and details. Move and delete the original and inspect both results.

Removing a shared calendar or copying connection

For private sharing, remove the other account's permission when access is no longer needed. For automatic copies, follow the tool's cleanup process and inspect remaining destination items before revoking credentials.
