10 Odd and Awesome 2013 Calendars

The calendar you hang on your wall or set on your desk can say a lot about what kind of person you are. And they make great gifts, as long as they appeal to the interests and personality of the person you're giving one to. Here are some unique 2013 calendars that will stand out in an office and draw lots of interest from those around you.

1. 12 Months of Dead Ken

12 Months of Dead Ken is a project by Sniperphotog, who describes himself as a "Doll Photographer with a subversive sense of humour" who poses Barbie and Ken dolls in extreme situations. The calendar features mostly scenarios of Barbie murdering Ken while maintaining that smile she is famous for.

2. Practicon Dental Supply Calendar

Practicon is a company that supplies dentists and dental schools with specialty items, from office equipment to simulation patients on which dental students can practice. The mannequins are the focus of the company's 2013 desk calendar. They are posed in seasonal scenes as if they are people! The calendars were given out to clients, but one dentist posted it to reddit, and Practicon responded by making the calendar available to the public.

3. Lindner's Coffins

Lindner's Coffins is a Polish wholesale coffin supplier. For years, the company has issued a calendar featuring their coffins with scantily-clad (and sometimes topless) models. The Catholic church is not amused, but the calendars are very popular. Their 2013 Calendar is available online. The cover is shown here because the images inside are NSFW.

4. Vancouver Ice-o-Topes

The Vancouver Ice-o-Topes are women hockey players with the Adult Safe Hockey League. For the third year in a row, members are baring a little more than usual in a calendar to raise funds for the Britannia Ice Rink programs in east Vancouver, which provide hockey training and games for underprivileged children. This year, the photos are set on the ice, which wasn't easy for the players, but the results are truly unique. Order a calendar at their site. Photograph by Rebecca Blissett.

5. The Periodic Calendar

The Periodic Calendar is a complete redesign of our traditional calendar based on the design of the periodic table of elements. Ape Con Joey can explain it better than I can (because I don't understand it).

6. How To Tell If Your Cat Is Plotting To Kill You

Matthew Inman of The Oatmeal released a book called How To Tell If Your Cat Is Plotting To Kill You. The adjunct is a wall calendar featuring Inman's cat illustrations and comics to keep you on track through 2013.

A Simple Trick For Figuring Out the Day of the Week For Any Given Date

People typically remember anniversaries in terms of dates and years, not days of the week. If you can’t remember whether you got married on a Saturday or Sunday, or don't know which day of the week you were born on, there’s a simple arithmetic-based math trick to help you figure out sans calendar, according to It's Okay To Be Smart host Joe Hanson.

Mathematician John Conway invented the so-called Doomsday Algorithm to calculate the day of the week for any date in history. It hinges on several sets of rules, including that a handful of certain dates always share the same day of the week, no matter what year it is. (Example: April 4, June 6, August 8, October 10, December 12, and the last day of February all fall on a Wednesday in 2018.) Using this day—called an “anchor day”—among other instructions, you can figure out, step by step, the very day of the week you’re searching for.

Learn more about the Doomsday Algorithm in the video below (and if it’s still stumping you, check out It’s OK to Be Smart’s handy cheat sheet here).

Big Questions
Why Was February Chosen for Black History Month?

Every February since 1976, the United States has celebrated the achievements of African-Americans during Black History Month. The month-long celebration puts those accomplishments and milestones in focus via the media and in classrooms.

But why February? Was that part of the calendar chosen for any specific purpose?

It was. Black History Month began as “Negro History Week,” a label applied by historian Carter G. Woodson in 1926. Woodson was bothered by the fact that many textbooks and other historical reviews minimized or ignored the contributions of black figures. Along with his Association for the Study of Negro Life and History—later the Association for the Study of African American Life and History—Woodson earmarked the second week in February to raise awareness of these stories.

Woodson chose that week specifically because it covered the birthdays of Frederick Douglass (February 14) and Abraham Lincoln (February 12). The ensuing publicity led many mayors and college campuses to recognize the week; through the years, the groundswell of support allowed the occasion to stretch throughout the entire month.

In 1976, President Gerald Ford made Black History Month official, saying that he was urging everyone to “seize the opportunity to honor the too-often neglected accomplishments of black Americans in every area of endeavor throughout our history.”
