How to Set an Anniversary Reminder on iPhone

Quick answer: In Apple Reminders, create a reminder, open its details, choose the anniversary date, set Repeat to yearly, and add an Early Reminder if you want time to plan. Apple Calendar is better when you want the date to remain visible as an annual event. A dedicated anniversary tracker is useful when you also want a countdown, milestones, widgets, and several special dates in one place.

An anniversary reminder should do more than tell you what you already know on the morning itself. The useful setup gives you enough warning to book, buy, write, or organise something—and then repeats next year without rebuilding it.

You can do that with the apps already on an iPhone. The important choice is whether the anniversary is primarily a task, a calendar event, or a date you want to keep watching throughout the year.

Method 1: make a yearly reminder in Apple Reminders

Use Reminders when the notification should prompt an action such as buying a card or booking dinner.

1. Open Reminders and tap New Reminder.
2. Give it a specific title, such as “Plan our wedding anniversary.”
3. Open the reminder's Details.
4. Turn on Date, then select the anniversary date.
5. Choose a time if you want the notification at a particular hour.
6. Tap Repeat and choose the yearly frequency.
7. Tap Early Reminder and choose how far ahead you want the first warning.
8. Tap Done.

Apple's current iPhone guide confirms that a dated reminder can repeat and can have an early reminder. Some Reminders features depend on using updated iCloud reminders, so the exact choices may differ if the list belongs to another account.

Pick a useful early-warning time

Choose the warning from the action you need to take, not from how important the date feels:

• One or two days before works for a message, flowers, or a simple local plan.
• One or two weeks before gives you time to arrange a meal, present, or childcare.
• One month before is more realistic for travel, tickets, reservations, or a personalised gift.

An early reminder is still tied to the same task. If you need a planning sequence—book, buy, confirm, then celebrate—create separate tasks for those steps rather than expecting one notification to carry the whole plan.

Method 2: keep it visible in Apple Calendar

Use Calendar when you want the anniversary to sit alongside the rest of your schedule.

1. Open Calendar, go to the anniversary date, and tap the add button.
2. Enter a clear event title and make it an all-day event if the occasion has no fixed time.
3. Set the event to repeat every year.
4. Add an alert before the event.
5. Save the event and check that it appears in the calendar you intend to keep using.

Apple documents event alerts and lets you choose default alert times for events and all-day events. Also check Settings > Notifications > Calendar if the event exists but you never see its alerts. If you use more than one calendar account, confirm which calendar owns the event before assuming it will sync everywhere.

Calendar is the cleaner choice for shared plans and schedule visibility. Reminders is the clearer choice when you need to complete an action. There is no harm in using both, but duplicate alerts become easy to ignore, so give each one a distinct purpose.

Method 3: use an anniversary tracker for countdowns and milestones

The built-in apps are enough if you have one annual date and simply need a warning. A dedicated tracker becomes useful when you want the date itself to stay visible between notifications.

Anniversary Tracker combines a day counter with an anniversary calendar, advance reminders, automatically generated milestones, and Home Screen and Lock Screen widgets. The public version lets you add special dates and choose whether each one repeats yearly.

To add a reminder in the iPhone app:

1. Open the Calendar tab and tap the large add button.
2. Name the occasion and choose its date.
3. Turn on Allow Notification.
4. Select the alert lead time and reminder time.
5. Turn on Repeat yearly for a recurring anniversary.
6. Save the date, then check the displayed next-notification time.

The current alert choices run from the day itself through one, two, three, or five days; one or two weeks; and one, two, or three months beforehand. Each saved occasion has one selected reminder, so use Reminders as well if you need a multi-step planning checklist.

You can download Anniversary Tracker for iPhone. There is also an Android version if your important dates live on a different phone.

Which setup should you choose?

What you need	Best starting point
One annual notification	Apple Reminders
A date visible with appointments	Apple Calendar
A task to complete before the date	Apple Reminders with an early reminder
A live countdown or widget	Anniversary Tracker
Several milestones and special dates	Anniversary Tracker
A multi-step plan	Several Reminders tasks

Start with the smallest system that solves the problem. If one yearly reminder is enough, use the built-in app. If you keep opening Calendar to calculate how long is left, or want 100-day and monthly milestones alongside the annual date, a tracker removes that repeated work.

Troubleshooting an anniversary alert that never appears

Work through these checks in order:

1. Open the saved item. Confirm the date, time, yearly repeat, and early-warning choice rather than assuming the save completed.
2. Check notification permission. In Settings, open Notifications and make sure alerts are allowed for Reminders, Calendar, or the tracker you chose.
3. Check the owning account or calendar. A work or third-party account may not support every iCloud feature and may sync differently.
4. Look at Focus settings. A delivered notification can be silenced or deferred by your current notification setup.
5. Avoid accidental duplicates. If Calendar, Reminders, and another app all alert for the same date, keep only the warnings that lead to a useful action.
6. Test with a nearby date. Create a temporary alert a few minutes ahead, verify that it arrives, and then remove the test.

No reminder system can guarantee that a notification will be noticed, but checking the saved trigger and notification permission catches the most common setup errors.

For a glanceable counter after the reminder is working, follow the anniversary countdown widget guide. If you are deciding which dates belong in the same system, browse 50 dates worth tracking or the wedding anniversary milestone list.
