How to Add a Subscribed Calendar on iPhone

An iPhone calendar subscription follows a schedule maintained by its publisher, such as a school's dates, a shift schedule, or club fixtures. The publisher controls the appointments; your Calendar app displays them beside your own.

Use a link from a source you recognize. If a webpage or pop-up says you must add a calendar to fix or protect your phone, ignore it. That is a common calendar-spam trick.

Add the subscription in Calendar

On iOS 26 and later, open Calendar → Calendars → Add Calendar → Add Subscription Calendar. Enter the address, tap Find, and choose a title and color. In iOS 18 or earlier, the same subscription menu uses Subscribe after you enter the address.

Choose iCloud under Account if you want the subscription on other devices signed in to the same Apple Account. Then save it using Done on iOS 26 and later, or Add on older releases. Apple's version-specific subscription steps show both flows.

A website's “Add to calendar” button may offer a single downloadable event instead of a continuing subscription. If you only see one appointment arrive, check whether the publisher offers a separate timetable or season feed. Look for a continuing subscription instead of a single-event download.

Dates, times, and the published range

After subscribing, return to Calendars and make sure the new calendar is selected. Find an event you recognize and compare its date, time, and location with the original source.

Check the next week or month too. A subscription can be valid while the publisher has only released a limited date range.

Use a recognizable name and color if those settings are available. When several calendars have similar titles, it is easy to mistake the subscribed schedule for one you own.

If a time looks wrong, compare the event's time zone with the source. Your phone displays timed events in its chosen local zone. Diagnose a one-hour difference separately from a missing update.

You follow the publisher's changes

A subscribed calendar is read-only. If a class changes rooms, the institution updates the schedule; you do not edit that original through your phone subscription.

Changes also depend on the subscription refreshing. For an appointment that moved today, check the publisher's schedule. If the phone still shows the old time, investigate where the subscription update stops.

Do not add the same feed several times to hurry an update. That can leave several identical-looking calendar layers and reminders. To see which copy you are looking at, hide the calendars one at a time.

Choose what should alert you

A reference calendar can become noisy if it contains every school activity or every fixture in a league. Review the calendar's available alert settings and decide which schedule should send notifications.

For an event you will attend, create a related personal appointment if you need travel time or private notes. Keep it separate from the publisher's event and review it if the fixture or class moves; your own appointment will not move with the feed.

To block a separate work calendar, add manual busy blocks for occasional commitments. For a changing feed, an Avum Sync Rule can read the ICS source and maintain copies in that work calendar. Copy only the time and details that belong at work. The phone subscription and the rule are separate connections to the read-only source.

Remove it when you no longer need it

In Calendar, tap Calendars, then the information button beside the subscription. Choose Unsubscribe or Delete Calendar, depending on your version. Make sure the confirmation names the subscription you want to remove.

Hiding the calendar is different from unsubscribing. If the events were also copied into another account, stop that separate process and review its copies independently.
