The fastest way to add a birthday to iPhone Calendar
Open the Contacts app, find or create the person's contact, tap Edit, scroll down to Birthday, and enter the date. When you save, that birthday automatically appears in your Calendar app on the person's birthday each year. You do not need to open Calendar itself to add the birthday — Contacts handles it.
If the person is already in your contacts but has no birthday listed, tap their name, tap Edit, scroll to Birthday, add the date, and save. The birthday will show up in Calendar within seconds.
You can also add a birthday directly in Calendar by creating an all-day event on that date and marking it as a birthday, but using Contacts is simpler because it syncs across your devices and links the birthday to the person's contact information.
Key Takeaways
- The Contacts app is where you add birthdays — find the person, tap Edit, scroll to Birthday, enter the date, and save.
- Birthdays added in Contacts automatically appear in Calendar as all-day events every year without you having to re-enter them.
- If you use iCloud, birthdays sync across your iPhone, iPad, and Mac so you see them everywhere.
- You can set up notifications for birthdays so you get a reminder on the day or a few days before.
Adding a birthday when you create a new contact
When you add a new person to Contacts, you can include their birthday at the same time. Open Contacts, tap the + button in the top right, fill in their name and phone number or email, then scroll down and tap Birthday to enter the date.
The date picker will show you month, day, and year fields. Enter the year only if you want to track their age — if you leave the year blank, the birthday will still appear in Calendar every year, but it will not show their age. Either way works; it depends on whether you want to know how old they are turning.
Once you save the contact, the birthday is live in Calendar immediately.
Editing or removing a birthday you already added
If you entered a birthday incorrectly or need to change it, open Contacts, find the person, tap Edit, scroll to Birthday, and tap the date field to change it. Make your correction and tap Done, then save the contact.
To remove a birthday entirely, open the contact, tap Edit, scroll to Birthday, and tap the X or delete button next to the date field. Save the contact and the birthday will disappear from Calendar.
Setting up reminders for birthdays
By default, iPhone shows birthdays in Calendar but does not send you a notification. To get a reminder, open Calendar, find the birthday event on that date, tap it, and tap Edit. Tap Add Notification and choose when you want to be reminded — options include the day of, one day before, one week before, or a custom time.
You can add multiple reminders if you want one notification a week ahead and another on the morning of the birthday. Tap Done to save your reminder settings.
If you want the same reminder for all birthdays instead of setting them one by one, open the Calendar app, tap the three-line menu icon at the bottom, go to Settings, scroll to Notifications, and look for Birthday notifications. You can turn them on or off here, though the timing options are more limited than editing individual events.
Birthdays from contacts you receive or import
If someone sends you a contact card (a .vcf file) that includes a birthday, and you add that contact to your phone, the birthday comes with it. Open the contact card, tap Add Contact, review the information, and save. The birthday will be there automatically.
If you import contacts from another phone or service, birthdays transfer over if they were included in the original data. Check a few contacts after importing to make sure the birthdays came through correctly, especially if you switched from Android or another iPhone — sometimes the date format does not translate perfectly.
Syncing birthdays across your devices
If you use iCloud, birthdays you add in Contacts on your iPhone appear in Calendar on your iPad and Mac as well. This happens automatically as long as you are signed into the same iCloud account on all your devices.
If you use Google Contacts or another service instead of iCloud, birthdays may not sync the same way. Check your settings in Contacts to see which account the birthday is being saved to — tap Settings at the bottom of the Contacts app and look at which account is set as default. Birthdays saved to iCloud sync everywhere; birthdays saved to other accounts may only appear on the device where you entered them.
Birthdays that appear in Calendar but not in Contacts
Sometimes a birthday shows up in your Calendar but you cannot find it in Contacts. This usually happens when the birthday came from a social media account linked to your phone, like Facebook. Open Calendar, tap the birthday event, and look at the details — it will show you which account it came from.
If you want to manage that birthday in Contacts instead, you can create a new contact for that person and add their birthday manually. The duplicate birthday will then appear twice in Calendar until you delete one of them.
Frequently Asked Questions
Can I see everyone's birthdays in one view in Calendar?
Calendar does not have a dedicated "all birthdays" view, but you can see them by switching to Month view and looking for all-day events at the top of each day. Birthdays appear as all-day events just like any other event you create. You can also search for "birthday" in Calendar to see a list of upcoming birthdays.
What happens if I delete a birthday from Calendar instead of Contacts?
If you delete the birthday event directly in Calendar, it will reappear next year because the source is in Contacts. To permanently remove a birthday, you must delete it from the contact in the Contacts app, not from Calendar.
Can I add a birthday for someone who is not in my contacts?
You can create an all-day event in Calendar on that date and name it "Birthday — [Person's Name]", but it will not link to a contact. The better approach is to create a contact first, add the birthday there, and let it sync to Calendar automatically.
Do birthdays show up in Calendar if I do not have the Contacts app open?
Yes. Once a birthday is saved in Contacts, it appears in Calendar whether or not you have Contacts open. The two apps share the same data, so the birthday is always there.
Can I change the color of birthday events in Calendar?
Birthday events use the default color for your Contacts calendar and cannot be changed individually. You can change the color of the entire Contacts calendar by opening Calendar, tapping the three-line menu, finding Contacts in the list, and tapping the colored dot next to it to pick a new color.
