We live in an age with countless - literally countless - national and international days, each one marking something even more obscure than the one before it, and all of varying degrees of legitimacy.
But every now and again we find one that we can all get behind... Like Bring Your Dog To Work Day, which, you'll be delighted to know, is today.
Photos are already flooding into social media this morning, with pooches rocking up everywhere from offices, radio stations and hospitals through to libraries, hotels and architecture firms.
Just look at these good doggos helping keep our streets safe:
There are even some extra paws helping out at the Tower of London:
The Trainline office looks like it's had a canine invasion:

The premise is as simple as it sounds: for just one day a year, people across the UK are encouraged to bring their dogs into work, which is obviously a great idea.
Sadly, it is not mandatory that all employers respect the sanctity of the day, so you'll have to check with your boss before you rock up to the office with your four-legged best mate in tow.
Fingers crossed they'll be up for it though - after all, the day is not only about boosting morale for animal lovers, but also about raising money for charity.
The idea is that people who take part donate to All Dogs Matter, which rescues and rehomes abandoned dogs, or to Animals Asia, a charity devoted to ending the practice of bear bile farming, as well as improving the welfare of dogs and cats in China and Vietnam.
Companies that take part are encouraged to donate £100 and will receive a shout-out online, while individuals who donate a tenner can upload a pic of their pooch at work to their 'Dog with a Job Hall of Fame'.

The other upside is that it simply makes people very happy, with new research from the University of Lincoln showing that employees who often bring their dogs to work report 22 percent higher satisfaction with their working conditions.
Dr Daniel Mills from the School of Life Sciences said: "If you told employers there was a simple way to increase their workforce overall satisfaction with the working conditions, they'd be very keen to learn more.
"Our results show that far from being a distraction (a fear expressed by some in our earlier work), allowing dogs in the workplace has the potential to improve employees' focus and probably productivity too.
"Forward-thinking companies should consider very seriously if they can accommodate dogs in the workplace and the Purina Pets at Work programme can enable them to do this efficiently."
