Facebook - love it or hate it, it’s changed the way we communicate and keep in touch with friends and family old and new.

But are you an occasional updater or a status addict? Now you can find out exactly how much time you’ve spent - or wasted - on the world’s biggest social network.

To celebrate Facebook’s 10th birthday on February 4, Time.com’s Tech section has created a calculator that tells you how much of your life you’ve devoted to Mark Zuckerberg and co’s creation.

Simply enter your Facebook email and login details so that the app can access your account. Don’t worry - the information isn’t posted on your timeline and your login details will be secure.

Facebook calculator results

Using the calculator we discovered we’ve spent 29 days, two hours and 53 minutes on Facebook since joining nearly seven years ago - a figure we’re fairly happy with.

The calculation is attained by running through the time stamps in your feed to find the earliest one, before using it to estimate your Facebook start date, so it’s not 100% accurate.

If you can tear yourself away from Facebook, head over to Time now.
