Black Mirror releases Hang the DJ's 'relationship expiry date' button for Valentine's Day

What a way to ruin the mood

Right on time, Black Mirror is here to ruin Valentine's Day.

Swooping in like the ultimate anti-cupid, the devious souls behind the Netflix series' marketing campaign have come up with a romance spoiler ripped straight from its own tech-terror universes.

Based on the season 4 episode, Hang the DJ, a new website claims it will calculate how long your relationship will last. All you need to do is copy the provided URL, send it your partner, and then press the button together to find out how long you have left.

The episode's original conceit imagines a world where couples are paired off and given the amount of time they have to stay together, before collecting their data to help them find their "ultimate compatible other".

Amy (Georgina Campbell) and Frank (Joe Cole) are paired for a mere 12 hours, but after a few brief encounters, they realise they're in love and try to rebel against the system.

Just like in the episode, if you check your own button without your other half, it automatically lowers your time together. What a way to spoil the mood.
