a serial date system starting on January 1, 4713 B.C.E.
If you wish to display the current ordinal date in a spreadsheet, such as a Microsoft Excel or a
Google Sheets worksheet you can use the formula below:
=TEXT(TODAY() ,"yyyy")&TEXT((TODAY() -DATEVALUE("1/1/"&TEXT(TODAY(),"yy"))+1),"000")
That formula will insert the current day in Julian format with a four-digit
year. E.g. for March 23, 2014, it would result in

The World Wide Web Consortium
is an international standards organization for the
World Wide Web (WWW)
Among the services offered by the W3C are a
Markup Validation Service
a CSS Validation Service
and RSS Feed Validation Service
The services are free.
validation service allows you to submit a
URL for a webpage to be
checked by the service or to upload an HTML file to be checked for
incorrect HTML code. If the code in a webpage is incorrect, you may not
see the results you expect for the webpage when it is displayed in a browser
or it may display incorrectly in some browsers used by visitors to the page.
The W3C tool will notify you of the types of errors on the page and the
line numbers on which they are found. You can match those lines numbers with
the appropriate lines in the code in browsers that allow you to view the
source code of a page.
You can provide a URL to the link checker tool and it will determine if any
of the links on the webpage are invalid.
The CSS validation service allows you to check the validity of
Cascading Style Sheets (CSS)
used on webpages to control the appearance and formatting of the pages.
You can provide a URL for a CSS or upload a CSS file to be verified.
The W3C Feed Validation Service
will check the syntax of Atom
or RSS feeds. E.g., if
you use RSS to publish updated information on blog entries, you can provide
the URL for the index.rss file on your site.
The W3C provides other tools as well at
Quality Assurance Tools.
All of the software developed at the W3C is Open Source / Free software, which
means that you can use the software for free and download the code, if you wish.
You can also modify the code to suit your own purposes, if you wish.
There is also a paid W3C Validator
Suite™, if you wish to have the W3C validate an entire site
automatically rather than you validating pages individually.
Note: the W3C validation services can't check pages that require authentication,
but can only check pages that are accessible from the Internet without
passwords or files that you upload to be checked.
