Leap Days DON'T happen every 4 years

It's true. While most years that are evenly divisible by four contain an extra day, years that are evenly divisible by 100, do not contain an extra day, except if that year is also evenly divisible by 400. That means that in a 400 year span, there are only 97 leap days, and not 100. 

Sound confusing? That's because it is. The calendar we use is pretty quirky. While a regular year is 365 day, a full year is actually something around 365 days and 6 hours. Thus, after four years, there are an extra 24 hours unaccounted for in the calendar. To make up for them, February the 29th is added.

However, the exact amount is not an exact 6 hours, but something like 5 hours, 49 minutes and 16 seconds. To compensate for that, the calendar doesn't add an extra day to years that end a century, unless that year also divides by 400. This means that the year 1900 didn't have a leap day. However, the year 2000 did, because 2000 can be divided by 400.

If you live long enough to see the year 2100, you'll be able to tell your great-grandkids that OMG Facts explained to you why 2100 doesn't have a leap day.

A man was ordered to apologize on Facebook or Go to Jail

In June 2011, Mark Byron, a photographer from Cincinnati, was found guilty of cilvil domestic violence against his wife and she was granted a temporary protection order. In November, Byron posted a note to his Facebook wall reading, ""If you are an evil, vindictive woman who wants to ruin your husband's life and take your son's father away from him completely -- all you need to do is say you're scared of your husband or domestic partner and they'll take him away!" 

 Byron had blocked his wife from viewing his Facebook page, however she still received word of the post and proceeded to file charges against her husband stating that his post was in violation of her protection order, which prohibited her [then] husband "from causing the plaintiff or the child of the parties to suffer physical and/or mental abuse, harassment, annoyance or bodily injury. On January 25th, Byron was given the option of going to jail for 60 days and paying a $500 fine, or pay back child support and post an apology to his Facebook page for 30 days.

A lightbulb manufactured in 1901 has been burning continuously ever since!

In Livermore, California, there is a lightbulb that burns bright in a fire station that has not been turned off (besides a few brief interruptions) for nearly one million hours. 

The bulb was donated in 1901 by Dennis Bernal, a pioneer in the area who once owned the Livermore Power and Light Co. It was first hung as a night light in a downtown garage so that the firefighters wouldn't have to worry about kerosene lamps. Then, it was moved to City Hall, before finally making its way to the old Fire Department Headquarters.

The more afraid you are of a spider, the bigger it seems to you!

Michael Vasey, professor of psychology at Ohio State University, found in his research that if you're afraid of spiders, you tend to perceive spiders as bigger than they really are. This may feed your fear, and make it difficult to overcome. 

It has been found that spider phobia affects 1 in 6 males and about half of all females. Participants of the study were asked to estimate the size of the spiders after each encounter. Researchers found that participants who were most afraid of spiders, also estimated the tarantulas' sizes to be largest

Lightning kills about 58 people a year.

These victims are usually those that are caught outside during thunderstorms. However, lightning has injured--and even killed--those who have been indoors. 

Lightning strikes into the ground near homes, sending jolts through pipes and into sinks and bathtubs. Not only do metal pipes serve as effective conduits for these electrical charges, but it has even been reported that individuals standing near windows and talking on landline phones have also been injured by lightning.
