Several Calendars

When does the new year of the Jewish Calendar start? Why are some Orthodox Churches celebrating Christmas in January? Which is the date of Easter this year? Answers to these, and many more questions are to be found in this project. Many calendars are treated here, beginning with the ancient Egyptian calendar, the the Roman and the French Revolutionary calendars to the Gregorian calendar, which is the calendar used in most countries. In addition, one can convert dates of several calendars with the Calendrical Calculator, and a section on the calculation of Easter is available, too. Using the Easter Calculator one can compute the date of Easter of a given year.

When did the new Millenium commence?

The beginning of the year 2000 was celebrated all throughout the world with major events. But, the determination of the beginning of our counting of the years was a quite deliberate act. There is nothing special on this 1 January 2000.

First, it must be mentioned that the third millenium only started with 1 January 2001. The first millenium began with the year 1, thus the last year of the first millenium was the year 1000, because a millenium has a thousand years. The year 1000 being counted as the first year of the second millenium would result in the first millenium having only 999 years. Therefore, the new millenium did not begin until 1 January 2001.

Secondly, in other calendars, our 1 January 2000 has totally "normal" dates:- It is in the Persian month Dey 1378; Jews record Tevet 5760, and the Islamic world celebrates the Ramadan of 1420.

Some Technical Remarks

Hints as "best viewed with browser_xyz and a solution of 1152x768" often tell us that, if we are not using the newest version of the most modern browser, we can only expect a screen with scrambled pictures - and maybe some text. I've tried to create pages that could also be viewed with a text-based browser. However, I'm not one of the puritans for which even a background color is too luxurious.

The calendar pages are using Cascading Style Sheets (CSS). With a browser not interpreting CSS, one can read it without problems however. Tests revealed that tables are not displayed correctly by certain text browsers. In some rare cases Unicode characters are used which are not properly displayed by older browsers. However, this should not make the text illegible. The main disadvantage using an older browser is the absence of JavaScript support, which leads to the calendrical calculator not working. Testing can be performed with a limited number of browsers only.

Nevertheless I hope that you'll enjoy the calendar pages even without a working calendrical calculator.

The excellent HTML-, CSS-, etc. documentation SELFHTML (http://de.selfhtml.org/, in German) of Stefan Münz has been of invaluable help to me in creating this web site.

(Almost) anything that's new in the calendar pages can be found in the Log.
