Clicking On The "Calendar Years" Link In The Main Link Bar For This Site Will Take You To The Current Year.

About The 28 Year Rotation Of The Calendars - Navagation Bar.

There are 14 calendars in use today. The 14 calendars are based on the 7 days of the week. January 1rst can and does start on each and everyone of the 7 weekdays. That is 7 calender years for the regular years and 7 calendars for the leap years. Totaling 14 calendars.

It takes 28 years for the calendars to go around in a circle. The 28 year rotation nav bar works within itself. If you use the nav bar to click through the 28 year rotation it will go through the rotation correctly. However…

Each leap year is only used once in the 28 year rotation. Each regular year is used 3 times in the rotation.

In order to create the nav bar I had to duplicate the regular years twice so that I would have 3 sets of the regular years.

All of the other navagation bars and link buttons in this site will only go to the first set of regular years. The other 2 sets are extras. That is why the 28 year rotation nav bar only works within itself.

In this way, if you want to click through the rotation and you are starting with a regular year, you will have to make sure you are starting with the regular year in the proper order of the rotation. As all other links will only go to the first set of regular years.

For example,

If you click on a link for the year 2023 from anywhere else other then the 28 year rotation nav bar it will go to the first set of regular years. However, the year 2023 is a regular year and it will actually be in the second set of regular years for the 28 year rotation, so it won't be in the proper order.

It will be the same calendar, but the year 2024 will not come next unless you start in the proper place of the rotation which will be in the second set of regular years, or the second regular year that starts on a Sunday on the nav bar.

If you start with a leap year, it will always be in the correct order for the 28 year rotation.

Update, January 2025;

I have changed the coding for the links. Now, if the current year is a regular year, (not a leap year), all of the links in this website for that year will go to the proper order in the 28 year rotation nav bar.

All of the other links for the other regular years will still only go to the first set of regular years. That means that it may not be in the proper order for the 28 year rotation nav bar. However, finding the proper order shouldn't be too difficult once you get the gist of it.

I update this site every year, at the beginning of the year, so that it will stay current. As I continue to update this site I will try to find ways to make it better. I can only do so much with it, because, that is just how the html code works.

Note that, with the Gregorian revision, the 28 year rotation is interupted / changes on the 3 non-leap years per every 400 years.

That is, for every 400 years, the zero year of the first 3 centuries are no longer leap years and become regular years which changes the 28 year rotation. This was neccessary in order to mathmatically put the human, earthly calendar on a more precise and correct count of the year(s) and,or to keep the calendar more acurate.

Further note that, I put two 28 year rotation nav bars on this website. One on the main page and one above the big nav bar buttons to the right. That way, when or if you use it, you can either look at the calendars on the main page or watch the nav buttons on the big nav bar change. Both views are a bit limited. If you had a really big monitor to view the whole page you could see a bit more.
