The Common Calendar uses the same twelve months of the year as we do now, but with different lengths. Every year will start on Sunday 1 January, and every quarter year (not just year, but... QUARTER YEAR) will be identical. The first month of each quarter year (January, April, July and October) will start on a Sunday and have 31 days, finishing on a Tuesday. The second month (February, May, August and November) will start and end on a Wednesday and will each have 29 days. The final month (March, June, September and December) will start on a Thursday and have 31 days, ending on a Saturday and thus allowing the following quarter year to begin on the Sunday previously mentioned. As a result, Christmas Day (25 December) and New Year's Day (1 January) will always, without exception, fall on Sundays.

With this maths, we see that the year contains only 364 days each year. So, how do we account for the fact that the solar year (the determinant of the seasons) lasts 365.242199 days? Simple. We insert an extra week in certain years, rather than an extra day. To determine which years have this extra day, we use the Base System. Due to the pattern of the solar year I have given the base number of -3 to the year 2009. So then which number goes to 2010? Under the Common Calendar, 2009 would have had 364 days, which is 1.242199 days less than the solar year. So we add 1.242199 to -3 to get the base number of -1.757801 in 2010. We continue to add this number to the year - but the number must ALWAYS be between -3.5 (inclusive) and +3.5 (exclusive). So, by the time we get to 2013, the base number is +3.210995. What happens in 2014, when the base number would be +4.453194? We must subtract seven to give 2014 a base number of -2.546806.

BUT, to be able to legitimately do that, we must insert an extra seven days in the year 2013. This is done through a week called INTERCALARIS, which is inserted between Saturday 31 June and Sunday 1 July, 2013. The days of the week are simply "Sunday of Intercalaris," "Monday of Intercalaris" etc. and are not numbered in the same way that the months have their days numbered. Intercalaris is not a month; it is an "intercalary week." These years are also no longer known as leap years but as "intercalary years." The name leap year probably originates from the fact that the calendar "leaps" over one day of the week (i.e. Christmas day was a Saturday in 2010 and a Sunday in 2011, but in leap year 2012 will not be Monday but Tuesday). Of course, this does not happen in the Common Calendar. To keep from mucking up business quarters and the like, Intercalaris will be a worldwide holiday. The seven day week will be preserved and the days will be named as they usually are in the week, but every day will be treated as though it were a Sunday. Basically all this means is that if your business closes on a Sunday normally under the current system, it will close during Intercalaris.

On the other hand, with Christmas and New Year fixed on Sundays, there will be no regular closing of businesses between Christmas and New Year as often exists in today’s society. It seems fair, though, that at Christmas and Easter, to aid family time and other similar things, that people be given a brief, standard recess of Friday to Monday (23-26 Dec / 6-9 Apr) over these times. Ideally, these dates could be legal holidays in all observing countries, but if not then I would propose that these recesses be given to standard workers in a similar way as the Christmas-New Year break is now.

Some people have proposed a system whereby the year is kept with the same number of days as our current, Gregorian calendar, with the 365th and 366th days of the year being proposed as "blank days" not belonging to any week, to keep the calendar the same from year to year. Religious leaders in the Abrahamic Religions, accounting the majority of the world's population (Christianity occupying 33% and Islam a further 20%, with Judaism being smaller) have formally rejected this on the grounds that it violates the structure of the Sabbath as God intended. Such a calendar will never be used formally - the opposition has always been, and will always be, too strong. One may say that this system of adding these numbers to a base year is much too complicated - but only if you have to do it! And you won't!! All you need to remember is that intercalary years take place every five to six years and keep an eye out for the calendar!! Let your servants in publishing take care of that for you while you relax!!!

One last thing will be tidied up - the "moon-wandering" Easter Sunday to different dates in the months of March and April. How annoying is that - never knowing when Easter is going to be from one year to the next. How badly did it throw you off in 2011 when Easter was the latest it had been in 68 years? Or back in 2008, when it was the earliest in 95 years? Under the Common Calendar, the date of Easter Sunday will always, without fail, be Sunday 8 April. While there are many difficulties dating the crucifixion of Jesus, most scholars will assert it was either on Friday 7 April, AD 30 or Friday 3 April, AD 33, making the Resurrection Day 9 April or 5 April. Neither of these dates are Sundays in the Common Calendar, and most Christians unanimously agree that this celebration needs to take place on a Sunday. Thus, I have chosen Sunday 8 April, which falls between the two dates. If your birthday is 6 April you will be upset as your birthday will always be Good Friday - but nothing can be perfect for everyone!!

As we can see - we are left with a calendar which is MUCH SIMPLER than the one we are left with now. Please support a conversion to this on 1 JANUARY 2023!!!
