Birthday Calendar is the best and most convenient way to keep track of your friends' birthdays. It is compatible with all the major social networks.

Using this app, you can easily find the birthdays of your friends and family members, whether on Facebook or on your phone.

Just install the app on your phone or tablet, and you will see all the birthdays right away.

This app will automatically link the contacts with your account’s birthdays if the name matched.

If the name is not the same, then you have to manually link the contact from the Profile Screen.

Also, the application will need permission to read contacts from the device.

Note: There are some launchers that don't allow any third-party widget, so it won't work for them.
