How to Add Birthdays to Google Calendar (and Get Reminders)

Where birthdays in Google Calendar come from

Google Calendar has a built-in calendar called Birthdays. You'll find it in the left sidebar under "My calendars" on the web, and in the calendar list of the mobile app. It isn't a calendar you fill by hand in the usual way: according to Google's help page on birthdays, it syncs from Google Contacts. Any contact with a birthday saved on their card shows up on that date, every year, without you creating a recurring event.

That design has a practical consequence. If a birthday is missing from your calendar, the fix usually isn't in Calendar at all. It's in Contacts, or in the setting that connects the two.

In September 2024 Google added a second path. You can now create and edit dedicated birthday events right inside Google Calendar. These are a distinct event type (the Calendar API calls it "birthday"), not a regular all-day event you've set to repeat yearly. The rollout started on Android, then reached the web and the iOS app in the following weeks.

So you have two options, and they're good at different things.

Method 1: Add a birthday to a Google contact

This is the cleanest option for anyone you already have as a contact, because the birthday lives on the person's card and follows them everywhere Google Contacts syncs.

Step 1: Open the contact. Go to contacts.google.com on a computer, or open the Contacts app on Android, and find the person.

Step 2: Edit and add the birthday. Click Edit, find the Birthday field (you may need to click "Show more"), and enter the date. The year is optional. If you include it, you'll know which birthday it is, which matters for milestones.

Step 3: Save. Within a short time the birthday appears in the Birthdays calendar on that date, and it will come back every year.

For many people, do it in one sitting: your most important contacts first.

Method 2: Create a birthday event directly in Google Calendar

For someone who isn't in your contacts (a colleague, a friend of a friend, a neighbor's kid), the birthday event type is faster.

Step 1: Start a new event. On the web, click Create. In the mobile app, tap the plus button.

Step 2: Choose Birthday. Alongside options like Event and Task, recent versions of Google Calendar offer a Birthday option. Pick it, enter the name and the date.

Step 3: Save. The event repeats yearly on its own. You don't need to set a recurrence rule, and it appears with the other birthdays.

If you don't see the Birthday option, your app may be out of date, or your Workspace account may not have it enabled yet. In that case a plain all-day event set to repeat annually works as a fallback. For the general mechanics of yearly repeats, see our guide to recurring events in Google Calendar.

Make birthdays visible: color and placement

A birthday you never notice is the same as a birthday you never saved. Two settings help.

Keep the Birthdays calendar checked. In the left sidebar, the checkbox next to Birthdays controls whether it shows at all. Google's help page notes that unchecking it is how you hide birthdays, which also means a stray click is the most common reason they disappear.

Give it a color that stands out. Hover over Birthdays in the sidebar, open Options, and pick a color you don't use for anything else. Birthdays are all-day items, so they sit at the top of the day, and a distinctive color makes them easy to spot at a glance. If you want a system for the rest of your calendars, our color-coding guide covers how to choose colors that stay readable.

Get reminders for birthdays

Seeing a birthday when you open your calendar is useful. Getting told about it when you don't open your calendar is what actually saves you.

Notification options for birthdays live in the settings for the Birthdays calendar and in the event itself, and Google has adjusted these menus over time, so check Google's birthday help page for the current path on your device. In general:

• For birthday events you created, open the event and add a notification the way you would for any all-day event. You can stack several: one a week before to buy a gift, one on the day to send a message.
• For birthdays synced from Contacts, look in the Birthdays calendar's settings for its default notifications. All-day notifications fire at a set time of day, so pick one that works for you.

A good rule: one reminder early enough to act (a week if you'll mail something, a day or two if you'll just call), and one on the day itself. A single reminder on the morning of the birthday is fine for a text, but too late for a gift.

Google Calendar birthdays not showing? Check these

If birthdays you know you saved aren't appearing, work through this list in order. It covers most cases.

• The Birthdays calendar is unchecked. Look in the left sidebar on the web, or the calendar list in the app, and make sure Birthdays is turned on.
• Sync from Contacts is off. Google's help page describes a "Sync from Contacts" setting under Settings, then Birthdays. If it's off, contact birthdays won't flow into Calendar. Be aware of the flip side: per Google, turning sync off removes the birthday events that came from Contacts.
• The wrong account is selected. If you use more than one Google account, each one has its own contacts. The birthday has to be on a contact in the same account as the calendar you're looking at, and the per-account checkboxes in the Birthdays settings need to be on.
• The contact has no birthday. Open the contact and check. Imported contacts often have a name and phone number but no date.
• You're looking in a different app. A birthday that shows on the web but not on your phone usually points to a sync issue on the phone side, not a missing birthday.

Seeing birthdays twice? Duplicates usually mean the same person exists twice: once as a contact with a birthday and once as a birthday event you created, or as two contact cards across accounts. Merge the duplicate contacts in Google Contacts, or delete the extra birthday event, and the doubles go away.

Getting Google Calendar birthdays onto your iPhone

If you use an iPhone, you have two ways to see these birthdays on the phone.

The first is Google's own Calendar app for iOS, which shows the Birthdays calendar like the web version does. The second is adding your Google account to the iPhone's built-in Calendar app. Our step-by-step guide to adding Google Calendar to iPhone walks through both options.

One detail trips people up: Apple Calendar has its own Birthdays calendar, which Apple fills from the birthday field in Contacts on your devices. If your Google contacts also sync to the iPhone, you can end up seeing birthdays through both routes. If you rely mostly on your iPhone, our guide to birthday reminders on iPhone covers Apple's side in detail, including alert times.

A simple system that works

You don't need a complex setup. Most people who never miss a birthday do three things:

• Store birthdays in one place. Ideally on the contact card, so they follow the person across apps and devices.
• Make them visible. Birthdays calendar on, with a color that stands out.
• Get two reminders. One early enough to act, one on the day.

The weak link is almost always the reminder. A calendar that shows birthdays but doesn't tell you about them only works if you open it every day.
