The year 2013 is an ideal time to learn this calendar method. We have 3 years without a leap year so it simplifies the system for learning. You will quickly learn Key Dates which all fall on the same day of the week every year. The Magic Day of the week these dates fall on changes in a simple way (most years step forward one day). Once you learn to find days for dates in 2013, you can just add one day for the same date is 2014 and one more day for 2015. Then 2016, a Leap Year, is also easy and makes sense.
