It's Friday, and for Japan's luckiest workers that means it's party time—by strict orders of the boss. Corporations are answering the government's call to let employees out at 3 p.m. on the last Friday of each month so they can hit up the bars and paint the town red. Some are even hiring limos for their employees and handing out cash. As well as being a good way to de-stress chronically overworked staff, "Premium Friday" could boost consumption by as much as $563 million a year, according to SMBC Nikko Securities.

Saudi Arabia's about to get a reality check on oil. The country has said oil giant Saudi Aramco is worth more than $2 trillion, enough to consume Apple twice and still have room for Google parent Alphabet. The kingdom may have to settle for less. A lot less. Industry experts told Bloomberg their analysis suggests Aramco is worth no more than half that amount, and maybe as little as a fifth.

How to survive the longest flight in the world. Qantas will begin flying a non-stop 9,000-mile route next year, which will take an eye-watering 19 hours. Whether you're planning to board one of these crazy long-hauls or simply dreading your next trip halfway around the world, here are a few coping strategies from frequent fliers who rack up hundreds of thousands of miles each year.
