Birthday Lookup: How to Find Out When Someone Was Born

Birthdays are an important part of every person’s life. However, we don’t always know when someone’s special day actually is. Whether it’s your old friend, a new colleague, or someone you’ve known for a very long time and want to congratulate, searching for birthday information isn’t difficult at all. It requires a little curiosity and sleuthing. But what are some of the most effective birthday lookup methods that won’t waste your time and will most likely be accurate? Let’s find out below.

Turn to People Search Sites

People search sites or people search engines are online tools where you can find information about a person, including their date of birth and other details like addresses, phone numbers, emails, and even criminal records.

To find someone’s birthday, you first need to open a people search website and enter their first and last name. Then, refine your search by adding a city and a state and click “Search”. From a list of individuals, choose the one that best matches the person you’re looking for and locate their birthday on the site.

If you’re curious, you can also look up other information, such as their relatives, marital status, and property info, among other things.

Search on Social Media

If the person whose birthday information you’re looking for is on social media, then what are you waiting for? Find them on the social networks where they’re registered and look up the necessary information.

On Facebook

Facebook is the perfect place to find this kind of info, as many people use it to share of types of data, including their birthdays. Here’s what you can do:

  • Visit the person’s profile page.
  • Check the info box under their profile picture, which typically displays their date of birth.
  • If this information isn’t visible, there are other ways to find it.

To find someone’s birthday, you can also:

  • Look through their past posts for birthday messages or celebration photos.
  • Review their timeline for any mentions of birthday celebrations.
  • Check if friends have tagged each other in birthday posts.

On Instagram

Instagram is another fantastic platform for finding birthday clues. Here’s how you can try to find someone’s birthday on Instagram:

  • Check their bio: Some users include their birth date, zodiac sign, or age directly in their bio.
  • Look through recent posts: Scroll through their feed to see if they’ve posted birthday photos, cakes, balloons, or captions like “Another year older” or “Birthday vibes.”
  • Explore tagged photos: Friends often tag people in birthday celebration posts, so check the “Tagged” tab for hints.
  • Watch Stories and Highlights: Many users share birthday celebrations in Stories, which might later appear in their Highlights.
  • Read the comments: Comments such as “Happy Birthday!” or “Enjoy your day!” can reveal the date or at least the time of year.

On X (Twitter)

X is a perfect platform to find out when someone was born. Here’s how you can try to find someone’s birthday on X:

  • Check their profile bio: Some users include their birth date, zodiac sign, or even their age directly in their bio.
  • Look under the “Birthday” field: If the user has added their birthday, it will appear on their profile — but only if they’ve chosen to make it public.
  • Scroll through their tweets: Search for posts with keywords like “birthday,” “bday,” “turning,” “another year older,” or “cake.”
  • Look for pinned tweets: Sometimes, users pin a post from their last birthday celebration.

On LinkedIn

LinkedIn might not be one of the platforms that comes to mind for finding birthdays, but it can be quite useful. Here’s how you can try to find someone’s birthday on LinkedIn:

  • Check the “About” section: Some users mention their birthday or birth month in their personal summary, especially if it’s relevant to workplace celebrations or milestones.
  • Look at the “Activity” tab: Around their birthday, people might receive “Happy Birthday” comments from colleagues or connections under their posts.
  • Browse their posts: Users sometimes share reflective birthday posts.
  • Check LinkedIn notifications: If you’re connected, LinkedIn may notify you of their birthday (though this feature isn’t always enabled for all users).

Ask Friends

One of the easiest ways to discover someone’s birthday is by asking mutual friends. If direct communication with the person isn’t possible, mentioning past birthday celebrations can prompt others to share their birthdays in return. Sharing your own birthday story can also encourage them to reciprocate with their details.

Talk to the Person Directly

This might not be the best idea if you’re planning to throw a surprise party or if you’ve known this person your entire life, but if nothing else works, why not?

If you don’t want to seem too direct, ask questions that feel casual and natural in conversation. Try asking things like:

  • “What’s your zodiac sign?” (This usually narrows down the date quickly.)
  • “Do you like celebrating your birthday or keeping it low-key?”
  • “I’m planning a birthday trip soon — when’s yours?”
  • “Do you share your birthday with anyone famous?”

Go Through Public Records

Many people are unaware that their birth date can be found through public records, but these records are generally available for public access and can be used to find different types of information.

Birth Records Search

Birth records are often the most direct way to discover someone’s birthday. These records typically include the child’s name, sex, date and place of birth, and the names of the parents. Begin by choosing the state where the birth occurred and accessing public record databases maintained by local and state governments.

Note that access to some birth records may require a request for proof of direct descent from the individual born.

Marriage Records Lookup

Marriage records are official documents that record the union between two individuals. Beyond listing names, marriage records often include key personal details, such as dates of birth, ages at the time of marriage, and places of birth.

Accessing marriage records can vary depending on the location. In some states or countries, these records are publicly available through government offices or online databases, while in others, you may need to provide a legitimate reason to request them.

Let’s Conclude: Final Tips for Finding Someone’s Birthday

People’s data is all over the Internet. Sometimes it’s surprising what’s available out there, but despite dangerous practices like identity theft, this data can be used for good. And birthdays are a great example.

When you don’t know where to look up a birthday, start with people search sites. Then, check a person’s social media profiles on social platforms. If you don’t find anything, it might be a good idea to talk to them or their friends or go through public records (online or offline, depending on the requirements).
