If you didn’t already know it the 1st January next year will always be on a different day to the 1st January this year. This comes about because:
for ordinary years with 365 days there are 52 weeks and 1 day remaining,
for leap years with 366 days there are 52 weeks and 2 days remaining.
This means that:
if the 1st January is on a Monday in an ordinary year then so is the 31st December. So the next year must have the 1st January on a Tuesday,
if the 1st January is on a Monday in a leap year then the 31st December is on a Tuesday. So the next year must have the 1st January on a Wednesday.
If there had been 364 days in every year the 1st January would always be on the same day of the week.
As a consequence of all this movement around the week, by the 1st January, next years calendar is always different to this years. That leads to the question: “There’s only seven days in a week so how many different ones do we need? Just seven.” Well the answer is, “No, you need another seven as well, for all the leap years. They too can start on any day of the week.” Continue reading “Fourteen Different Calendars”
There are fourteen different calendars required to make calendars for all years. Below is a Fourteen Calendar Table with all fourteen calendars labelled A to N. It shows for example:
which years have the 1st January falling on Mondays when they are NOT Leap Years, e.g. 2001, 2007 and 2018. These require Calendar (CAL) A.
which years have the 1st January falling on Mondays when they are Leap Years, e.g. 2024, 2052 and 2080. These require Calendar (CAL) H.
So that the table is compact the years listed for Calendars A to G are grouped into 4 x 21 cell bundles and a 22 cell bundle. For the most part each bundle has the years in numerical order from top left to bottom right.
Years listed for Calendars H to N are in simpler lists.
The tables scope covers 140 years from 2001 to 2140. A larger image can be seen by selecting it.
Remember: Leap Years are those with an extra day at the end of February on years where the number made by the last two digits of the year can be divided by 4. The year at the turn of each century would be a Leap Year but it has different rules. It’s normally not a Leap year but at a millennium like the year 2000 it was a Leap Year.

Viewing or Printing A Calendar For Any Year
If you want to view or print a calendar you may need to install a Portable Document Format (PDF) file reader browser add-on.
Installing A PDF File Reader Bowser Add-on
A browser add-on for viewing PDF files may need to be installed on your computing device. You can get Adobe Reader DC for Microsoft Windows PC’s and maybe for Mac’s from Adobe by following the link from the web logo below:
WARNING:Be careful to uncheck (untick) any premade selection for other applications offered for download by Adobe unless you DO want to install them too.
Look along that years row to the left and find its letter in the 2nd column headed CAL,
From the Table Of Calendars In Portable Document Format below you can select the letter A to N of the calendar you wish to view or print. Each calendar has 6 pages in Portable Document Format (PDF) which should be displayed in your browser in another tab.
You may be able to print the six pages to your satisfaction straight from your browser. You need to be proficient in using both your printer and browser to get a good result.
I am currently using Microsoft Edge (browser). That will do it but it shrinks the pages a little so that the white calendar border is kept unnecessarily within my printer’s margins. (My printer is an HP Photosmart B8350.)
Printing Method 2
By right clicking the browser view of the PDF in Edge I can select the option to Save the PDF to disk. I can then view it using Adobe Reader DC. That gives access to my printer options so that I can make borderless prints and choose the paper size (A3 or A4).
Printing advice when using Adobe Reader & Internet Explorer
If you do use Adobe Reader and use Internet Explorer but can’t find a toolbar from which to print, just move the pointer down to the bottom centre of the browser and a transparent floating toolbar should appear like this:
Look for the printer logo (2nd from the left) on that toolbar.
Select (click) on the Adobe logo at the right end of the toolbar and a permanent Adobe Reader toolbar will appear at the top of the page. Alternatively select print from the browser tools. You may get the same functionality.
When Print is selected you will get the opportunity to adjust your printer settings.
If you do have an A3 printer you will have to choose which size paper you are actually going to print on so familiarity with your own printer and its settings will be required. I advise you print one page to begin with and check it is how you want it. If possible set your printer to print to the edge of the paper with no margin to get the maximum size calendar.
Using Older Printers
If you have an older type of printer which isn’t capable of printing to the edge of the paper it will print within some margins. Within the printer settings these margins can usually be adjusted. So adjust them to their minimum settings, e.g.:
Top Margin = 3mm
Left Margin = 3mm
Right Margin = 3mm
Bottom Margin <= 15mm
Print The Top Of The Page First
Make the most out of the wasted paper which is the bottom margin. Many printers create a bottom margin as they hang onto the end of the paper as it comes out of the printer. This enables them to maintain control of the paper as they print the last lines.
Do this by rotating the image before printing so that the top edge of the calendar which will be stapled is formed by the bottom margin.
Rotating The Image
When the calendar is being viewed in the browser use the rotating tools within the PDF Reader to rotate the image through 180º, so that it is upside down. Then it may be possible to print so that all the printer margins fall within the white border of the calendar. Under these circumstances the bottom of the calendar will come out of the printer first and the top of the calendar, where the largest white border on the calendar is, will be printed last at the bottom of the page where the deepest printer margin is.
With any luck the whole calendar will get printed without any part getting truncated by the printer borders. This will put the 15mm margin at the top of the calendar where it has to be stapled and have holes punched in it.
I have formatted the header of each month so that there is space to the right of the month name to manually write the year number if required. I’m sure it’s only necessary to write the year on January’s page just to distinguish one year’s calendar from another when there is more than one lying about.
NOTE: The appropriate calendar reference letter is printed on each page to the far right of the month.
