Mars could have a Leap Day like Earth but way more complicated
February 29, “leap day”, is an oddity on the calendar that occurs every four years in an attempt to sync up the Gregorian calendar (the calendar most of the world uses to keep time) with Earth’s rotation around the sun.
One calendar year on Earth is 365 days long; however, the Earth actually takes 365.2422 days to lap the sun. That puts the planet roughly a quarter of a day behind at the end of each year.
To maintain consistency and ensure the seasons line up each year, an extra day was added to the already short month of February — a modification that happens every four years. But even this doesn’t fully solve the problem; additional tweaks are needed.
For instance, if a year is divisible by 100, there’s no extra day — unless the year is divisible by 400. That means that 1700, 1800 and 1900 did not have a leap day, but 2000 did. This adjustment ensures that Earth is as close as possible to the same point in its orbit in consecutive calendar years and keeps our seasons inline.
Unsurprisingly, Earth is not the only planet that needs leap days. The phenomenon could occur on other planets in our solar system as well as those around other stars. That’s because you can’t fit an exact number of spins into one trip around the sun for any planet. There’s usually going to be something left over. Leap days on other worlds, such as Mars, could be more complicated than those here on Earth.
One year on Mars lasts for approximately 668.6 Martian days. (A Martian day is called a sols and equals 24 hours, 39 minutes, and 35.244 seconds.) Future inhabitants might decide that a year on the red planet will be described as 668 days. How do we adjust?
Over the decades, many different ideas for the Martian calendar have been proposed. The most popular one, called the Darian calendar, was created in 1985 by Tomas Gangale.
According to Gangale, the Martian calendar would feature 24 months, each named for the Latin and Sanskrit words for the constellation of the zodiac, like Sagittarius and Dhanus, and so forth. The first five months in each quarter would have 28 Martian days (or sols), with the sixth having only 27. Even-numbered years would total 668 days and odd-numbered years would have 669. The exception to that rule: even-numbered years that were divisible by 10.
Another option was proposed by Michael Allison, a retired NASA scientist. In his version, the Martian calendar would have 668-days divided into 22 months, each totaling 30 or 31 days, similar in fashion to Earth. To make sure the seasons lined up, all years divisible by five will have three leap days, bringing the total to 671.
So which of these calendars do scientists use to keep track of time on Mars? Currently, none.
Instead, they use two systems to keep track of time: one counts the number of Martian days since the start of a mission, and the other keeps track of where Mars was in its orbit at that time.
Right now scientists don’t care if the seasons line up perfectly with the calendar, but that may change when you add humans into the mix. NASA and other space agencies around the world have their sights set on Mars. Once humans land on the red planet and spend significant time there, we are going to need a common calendar to keep track of seasons.

Tesla Cybertruck slapped with world’s least intimidating ticket, and it’s pure cringe
One cannot help but cringe and feel second-hand embarrassment at the idea of a person just driving around with a stack of these babies.

A Cybertruck parked at Stanford Shopping Center in California was recently hit with what might be the most try-hard piece of paper ever slipped under a wiper blade: a “fake citation” accusing the driver of supporting a “fascist car.”
The note, shared on X by Tesla staff program manager Ryan Torres, quickly made the rounds on X, where it quickly gained attention as an example of how not to protest.
The world’s least intimidating ticket
According to the citation, the supposed “violation” was “driving a fascist car.” The remedial action? Take the bus, call an Uber, or ride a bike. The note also dubbed Elon Musk a “chainsaw-wielding Nazi billionaire.” Now, protests against Tesla and Elon Musk have become commonplace this year, but one cannot help but cringe and feel second-hand embarrassment at the idea of a person just driving around with a stack of fake anti-Tesla/Musk citations.
Torres pointed out the irony himself in his post on X. Tesla currently employs over 140,000 Americans, and SpaceX has put the U.S. firmly back at the top of space technology. As Torres put it, maybe the person behind the world’s least intimidating ticket should “read a book on innovation before vandalizing” other people’s property.
Peak performative clownery
Not to mention that the fake ticket’s logic collapses under its own weight. EVs like the Cybertruck are literally designed to reduce emissions, not “destroy the economy.” If anything, Tesla has bolstered the United States’ economy by fueling jobs in engineering, manufacturing, and clean energy. It’s not the first time a Tesla has been the target of vandalism or politically charged notes, but this one stands out for sheer cringe value.
Torres summed it up neatly: “Peak clownery.” On that point, at least, the citation earns full marks. In a way, though, perhaps cringe fake tickets are not as bad as the literal firebombs that were being thrown at Tesla stores and cars earlier this year because some critics were gleefully misinformed about Elon Musk.

Why a Tesla Model Y led to a teen’s failed driving exam in Ontario
The issue was due to the driver using the Model Y’s regenerative braking system.

A North Bay, Ontario man has raised concerns after his teenage daughter failed her G driver’s license road test while driving his Tesla Model Y. The issue, the Tesla owner noted, was due to his daughter using the Model Y’s regenerative braking system to bring the car to a stop.
Regenerative braking bias
Eric Simard, the Tesla owner, told CBC News that his daughter borrowed his car for her driving test. Because of this, she was not fully familiar with how to disable the Model Y’s regenerative braking system. Unfortunately, the examiner did not allow his daughter to call him for help in turning off the feature.
Simard noted that his daughter ultimately failed her driving test because she never used the car’s physical brake pedal. In his daughter’s road test results from Drive Test Ontario, the examiner marked a box stating that the Model Y was “out of order.
“I find it pretty frustrating because even though it’s regenerative braking and you’re not using the brake pedal, you’re clearly the one that is in full control of making the vehicle come to a stop or to slow down,” Simard stated, adding that his daughter was also penalized for the Model Y’s feature that alerts drivers when a traffic light turns green.
Discussions on driver-assist technologies
In a comment, Julia Caslin, a spokesperson for Ontario’s Ministry of Transportation, stated that the province’s graduated licensing system “requires drivers to always demonstrate safe vehicle operation and full control, regardless of the vehicle’s features.”
“Applicants are expected to understand how their vehicle’s system — including lane centring, regenerative braking, adaptive cruise control and automated parking — may affect handling and performance during a road test,” Caslin stated.
Driving instructors also expressed differing views about Simard’s experience. Saad Tariq of Greater Sudbury Driving School said he advises students against relying on driver-assist features because sensors can fail.
Meanwhile, Amanda Lacroix of Northern Lights Driving School suggested road tests should adapt to the technologies drivers use daily, while still requiring mastery of basic skills like mirror checks and manual braking.
“If the world’s going to change and we’re all going to have assisted driving, then we should be learning how to do it properly,” Lacroix said.

Tesla says it is working on rides for the handicapped and disabled with Robotaxi
Tesla CEO Elon Musk confirmed that this was a focus by responding, “Absolutely,” to the embedded post on X above. Tesla said it is developing its own “wheelchair-accessible vehicle,” also known as a WAV.

Tesla says on its Robotaxi app that it is working on enabling “accessibility rides” that would give the handicapped and disabled the ability to hail a Robotaxi to get to an appointment.
While Robotaxi will obviously revolutionize the way we travel for our work commutes, daily activities, and other things, but there is true potential to enable serious change for those who cannot drive.
Autonomous transportation would make life easier for those who are unable to obtain a driver’s license. Of course, with today’s ride-sharing platforms, things are much easier than they once were.
However, rides from Uber and Lyft, while plentiful, always have an opportunity to be unavailable in some regions, especially rural ones, due to a lack of drivers.
Robotaxi aims to solve this problem through autonomous transportation, a technology that Tesla has been developing for years.
However, new language in the Robotaxi app shows that Tesla is working on a solution for people who need rides for medical reasons, and it uses a picture of the Robovan to hammer this point home:

This is likely the Robovan, which was unveiled on October 10 at the Robotaxi event last year:
It is pretty interesting to see two Musk ventures working on solutions for those who are physically impaired or have other disabilities. With Tesla, Robotaxi will unlock immense potential for those who are unable to drive themselves, addressing a genuine need in today’s world.
Additionally, Neuralink is continuing its development of technology to fight against various physical and mental disabilities. A great question to ask is, “Which will be more beneficial for humans?”
