How to Read the Mayan Calendar

The Maya actually used three different calendars.

  • The first was the sacred calendar, or Tzolk'in, which lasted 260 days and then started over again.  This calendar was important for scheduling religious ceremonies.
  • The second calendar was the Haab', or secular calendar, which lasted 365 days but did not account for the extra quarter-day that we have leap years to compensate.
  • The final calendar was the Long Count Calendar — the recording method that has caused all of the doomsday brouhaha of 2012.  On Dec. 21 this calendar completes a major cycle, which has triggered doomsday fears and mystical rumors about the end of an age.


Mayan CalendarHow the Mayan Long Count Calendar works
The Long Count Calendar may not predict doomsday, but it is good at covering long periods of time. Here's how it works:

Dates are written out as five numbers separated by four periods, such as  The right-most position is called the k'in, which counts single days:, for example.  The k'in counts up to 19 and then flips back to zero, with counting picked back up by the second position, the uinal.  So would become, much like a car’s odometer.

Each uinal is thus a block of 20 days.  The k'in position then picks back up, counting up to that 20, which then gets added to the uinal counter.  So the day after would be and then, all the way up to and finally

The uinals count upward as well.  While the Maya generally use a base-20 counting system, they modify this slightly for the uinal, which only counts up to 17 before rolling over to the third position, the tun.  Each tun is thus 18 blocks of 20 days, or 360 days — approximately a year by our solar calendar.

Tuns, in turn, count up to 20 before rolling over into k'atuns.  As 20 blocks of 360 days, each k'atun translates into 7,200 days, or just less than 20 years. The k'atun place then counts up before rolling over into the final digit, the b'ak'tun.

December 21st, 2012 marks the end of the 13th b'ak'tun of the Maya Long Count Calendar.  It's the day the counter will read On Dec. 22, it will read

Pretty cool system for an ancient civilization.........

Making time for your Kids

Average: 4.5 (4 votes)

Developing a strategy for becoming a better dad can sound like a big joke. To use the term “busy dad” in the current world is really an understatement. A lot of us dads have a difficult time trying to balance our professional or personal demands against spending valuable time with the wife and kids too. Just because your schedule is tight should not mean that you are destined to fail as a parent. 

Treating Back Pain at Home

No votes yet

back massageFor a long time now I have suffered from occasional lower back pain. Lifting heavy loads; twisting; and basic over exertion have all taken their toll on my back. Sometimes it’s even comical (though still painful). Like the time I was reaching for the toilet paper and bam, out goes the old man’s back. Seriously, what sadistic person mounts the roll behind you on the wall at shoulder height? If your spouse comes to help you in this position, you really know their love will last a lifetime. So here is how I fix my own back pains at home…

BusyDads Busier in 2012

As the name would suggest, we at 4BusyDads (being in large part BusyDads ourselves) understand what it means to be a dad in 2012. While it may seem obvious, the sheer chaos of our lives prevents us from fully appreciating the forest for the trees.

Fortunately, the good people at* and* have taken the time and energy to quantify this harried life with what refers to as the "Father's Day Index". This tongue in cheek effort strives to categorize and value the things that dads contribute at home. The results are clear. Don't quit your day job.

Using a Solar Charger for your RV or Camper

Battery camping solar charger

We like to camp. It started in Arizona when my wife and I were just dating (young, dumb, and broke). Our level of funding and experience dictated throwing a tent and supplies into the SUV and heading up into the mountains. We have since progressed on to a popup trailer, and now own a small Hybrid camper - although at 25 feet long some may disagree that it is small or “camping”. We park it at our Christmas Tree farm and have our own private campsite there too. The problem is we have no power or utilities way back at the camp. So I decided to set up a solar charging station to keep the camper batteries fully charged. Here’s how…..

The Fundamentals of “Patty-Cake”

No votes yet

Patty-cake, patty-cake, baker’s man. Bake me a cake as fast as you can. There I am, sitting in my dad’s lap with legs crossed, rolling and patting the dough. I wriggle with excitement as my favorite part gets closer when Dad will “mark it with a ‘K,’ just for me.” As he traces the first letter of my name into the imaginary cake, I grab his finger and imagine the letter on its surface in bright pink frosting, which I always tell him to use. Now put it in the oven for Daddy and me.
