Month 13 is out of bounds – one of the funniest computer errors ever

Month 13 is out of bounds, this funny error-message first appeared in December 2017, on the device log & console of a lot of macOS devices. The error has been reported by a lot of different applications, but mostly by third-party applications, thats why i think, that there is/was an error with the communication of the kernel and these applications!

So these applications thought that the December, would be Month 13. To manage processes, any application needs an timestamp and the most applications also need the date, so that they can work correctly.

The error appeared whenever these applications where running and the only problem with that is, that sometimes this message was displayed multiple times in a second. Interesting was, that this error mostly happened, whenever the cpu and ram usage was high.

The error message was also displayed (@ my iMac) in the beginning of January 2018, but at this time it was not as funny, as in december.

Why? Because its the 1 month in the year and it would be possible, that the 13 months would stand for the months, since the application has been installed, but it was not.

When you observe other errors and log messages, you can see, that sometimes RAM errors happen, while the Month is out of bounds error, is posted. An code error of the applications is not logic, because on my iMac, over 20 applications displayed the error, this makes it pretty clear that the error is not caused by an code error, of any third party applications developer.

The normal system time is not affected by the error, wich means, that the clock displays the real time. NTP (Net Time Protocol) is also working without any problems. So there are to reasons, for the error left: The first would be, that theres an error with an api, that should send the time & date to the applications, or theres an error in the ram. Anything that needs to get used fast, like the date, is saved @ the ram.

Normally, the OS writes the date in to the ram, during the booting-process, so it would be possible, that the os just wrote the false date into the random access memory. But I don’t think so, because the date, of the lower levels of the os, is correct.

On a website, I found the information, that rewriting (has to be done in sudo, but carefully, a false date-formate could damage the system) the date (using the terminal), would reduce the problem.

So I tried it on my iMac and it worked.

After resetting the date and a restart, the error never appeared again. Due to the fix, it is possible, that there was an error with rewriting the date, from the os level, to an for the applications accessible area. Fortunately, there is no permanent damage due to the defect.

This error, is not a big thing, it`s just funny and not dangerous.

Fashion Tips for Winter: The Right Way to Wear a Pashmina

Pashmina scarf

The Pashmina scarf made its grand debut in the western world in the late ’90s, but it’s still a stylish and fashionable look for winter trends, serving as a shawl, wrap, and simple accessory. If you’re looking for a new way to accessorize this year, consider adding a luxurious pashmina to your closet with a little background on its roots, and a few fashion tips for winter.

What is Pashimina, Anyway?

Pashmina is a blend of high quality silk and wool, and the source of wool is derived from goats that are bred and raised in Central Asia. Pashmina is easily found in Pakistan, India, and Chinawhere it’s been used as a shawl and coverup; the softest Pashinas are a blend of wool and silk, and offers plenty of comfort and warmth for chilly days. Finding an authentic Pashmina scarf can be challenging, and you’ll notice the difference in the texture and overall feel of cheaply made wraps as a result.

Fashion Tips for Wearing Your Pashmina

A pashmina can be the perfect way to top off an outfit and keep you cozy and warm for a blustery day ahead. Here are a few styles that work with this year’s trends:

1. Go Hollywood style. This is the easiest way to wrap yourself up in a pashmina with a simple scarf-style arrangement. For this look, you just wear it like a real scarf around your neck, except you twist it with two different colors for contrast. It pairs really well with a fashionable watch, like this one from Great Watches.

2. Make a noose. This is the classic look that is becoming even more popular this season; the ‘noose’ is created by folding the pashmina until it reaches a quarter of its original size, then tying it around the neck to form a loop. Simple and chic, this is an easy look when to pull off when you’re on the run.

3. Wear it as a stole. This is the perfect coverall when you’re not sure if you need a cardigan for a night out; the stole covers your entire upper body and makes the pashmina the center of attention.

4. Turn it into a full wrap. This one wraps around your shoulders and ties in the front, around your waist. It’s another way to make the pashmina take center stage for your outfit, and easily replaces a cardigan or vest.
5. Wear it as a belt. Your pashmina can be draped around the hips or waist and tied to the side to serve as a belt. It’s a simple addition to a one-color outfit, and you can contrast bold and bright colors with a monochrome outfit for a chic and fashionable look.


The Pashmina can be a great alternative to simple cardigans and bulky sweaters this season, and you’ll find it in different colors, prints, and beaded variations. Try a new look this winter with these tips, and enjoy the comfort of cashmere in a new way!
