How to Know the Birthday of a Person with Gmail ID?

A birthday is not a public piece of information that one can show off. It isn’t even displayed publicly on an internet profile unless the user wants to share it. So, this following technique is not actually a hack but the feasibility of the Google/Gmail technological interconnection.

Expected reader’s knowledge level: Smartphone users, Gmail ID account holders.

Everyone has an email ID today because of smartphones. As an android, which takes 80+ percent of all smartphone users, needs a Gmail account integration to work with the promised functionality. This integration is synchronizing the data onto Google clouds eventually.

So, keep that in mind as I walk you through the process of finding out the birthday of a person with a Gmail ID.


If you ever wanted to know the birthday of a person and you know their email ID (Gmail), just add them to your contacts.

If you are even closer to them and have the rapport to communicate over email. Send them a how-about email and let it be added to your contacts automatically.

You don’t need to add them specifically if communication is established on both ends with that email ID. By this, their email ID will be added to your contacts.

Now, take your android phone and add the email ID of that person to his number in your contacts (if had any).

Go to sync settings and sync Google calendar with your native calendar app. This will synchronize all the important dates and birthdays onto your mobile phone calendar.

Now open the calendar app on your Android phone and check what has been updated. You would see new birthdays added to your calendar. If you had added the email ID to the phone number, it would be much easier to identify the birthday of that person. It will then show the birthday with the name that you have given in your contacts to him/her.

It’s that simple!
