Date Functions & Usage

JIFDateFormatCode.js – The main Javascript code. MUST be specified in head section of web page.

=================================================================

To format Date/Time elements you wish to displayed on a web page.

requires the following in the head section of each html page

   <script type="text/javascript" src="inc/JIFDateFormatCode.js"></script>

You may use a predefined script in the body section where date time stamp is required.

  <script type="text/javascript" src="inc/StampDateTime.js"></script>

The result is displayed below with centred formatting

You may include additional text as below: (in red)

This page was loaded

The date may be output in BOLD if desired as follows.

Today is


OR You May Choose

Custom date elements from the table above.
Following is sample code in the body section of your page, where date output is required.
(YOU may wish to select different date elements from the above table)


<script type="text/javascript">
var myDate = new Date();
document.write(myDate.format('F jX Y \\p\\a\\g\\e\\ \\l\\o\\a\\d\\e\\d \\@ h\\:i A')+'<br>');
</script>

displays the date as below



OR simple code for simple elements such as month date Year

Predefined Date/Time Stamps

Requires the following in the head section of every html page using Date/Time elements.

   <script type="text/javascript" src="inc/JIFDateFormatCode.js"></script>

Both of these have line break at the end (any following text appears on new line)


Predifined date stamp: – inc/MyDateTimeStamp.js with results below (always BOLD)
Script file is hard coded for BOLD output. There are better ways to create bold output but this is just a sample of "how to". Requires the following at the location this date/time stamp is to be used

   <script type="text/javascript" src="inc/MyDateTimeStamp.js"></script>

Result is:

Code looks like this

   
    <script type="text/javascript">
      var myDate = new Date();
      document.write(myDate.format('<b>'+' l\\, F jX Y \\@ h\\:i A')+'</b>');
    </script>

Predifined date stamp: – inc/StampDateTime.js with results below (uses regular text)
Requires the following at the location this date/time stamp is to be used

   <script type="text/javascript" src="inc/StampDateTime.js"></script>

The output result is:

Code looks like this

   
    <script type="text/javascript">
      var myDate = new Date();
      document.write(myDate.format(l\\, F jX Y \\@ h\\:i A'));
    </script>


Predifined Today's date (Month daysuffix): – inc/TodaysDate.js with results below (uses regular text)
Requires the following at the location this date/time stamp is to be used

   <script type="text/javascript" src="inc/TodaysDate.js"></script>

The output result is:


Predifined Date (Day Month datesuffix): – inc/DayMonthDate.js with results below (uses regular text)
Requires the following at the location this date/time stamp is to be used

   <script type="text/javascript" src="inc/DayMonthDate.js"></script>

The output result is:


Predifined Date (mm/dd/YYYY): – inc/TodayIs.js with results below (uses regular text)
Requires the following at the location this date/time stamp is to be used

   <script type="text/javascript" src="inc/TodayIs.js"></script>

The output result is:


You may combine two or more sripts if wou wish inc/DayMonthDate.js followed by inc/TimeOnly.js

Today is this page was loaded at


Display the day number of the current year as inc/daycount.js – No line feed before but line feed after.

The output result is:

Can be combined with other scripts:
Today is inc/TodaysDate.js, inc/daycount.js
With the following result:

Today is ,


ISO Date is used throughout the world to eliminate confusion with various date formats. Using Apr or April works in English but not so well in French, Japanese etc...

03/06/02 Without firm standards, can and has been interpreted as

March 6th 2002 (US Usage (mm/dd/YY) - another example of US wnating to be different. I have always used this format (worked for US company))

June 3rd 2002 (UK & Canadian Usage (dd/mm/yy) and others used this format for centuries).

2nd of June 2003 – (yy/mm/dd)
Many forms specify the sequence that must be used to avoid confusion.


ISO Date Time

The ISO standard used throughout the world is YYYY-MM-DD
Some Europeans used YYYY.MM.DD before ISO and probably still do.

Back in the early days of computers, when every byte of memory was crucial, since memory was expensive and most computers had in the neighbourhood of 16 Kb total; unlike today with several megabytes at their disposal, two digit years saved significant resources. Today of course memory is not only cheap but abundant, facilitating four digit years without a second thought. Usage of two digit years has been typically a North American phenomenon. Using the four digit year certainly eliminates any ambiguity.

Predifined ISO Date (YYYY-MM-DD): – inc/ISODate.js results below
Requires the following at the location this date/time stamp is to be used

   <script type="text/javascript" src="inc/ISODate.js"></script>

The output result is:


ISO Time format is based on the military time format. Using the 24 hour time as opposed to the british AM or PM designation avoids ambiguity throughout the world.
ISO uses : to seperate time elements HH:MM:SS whereas military time does NOT.
ISO Time could be 23:15:00 military equivalent is 231500 (11:15:00 PM)

Predifined ISO Date/Time (YYYY-MM-DD HH:MM:SS): – inc/ISODateTime.js with results below
Requires the following at the location ISO date/time stamp is to be used

   <script type="text/javascript" src="inc/ISODateTime.js"></script>

The output result is:


Predifined ISO Time (HH:MM:SS): – inc/ISOTime.js with results below

Requires the following at the location ISO time stamp is to be used

   <script type="text/javascript" src="inc/ISOTime.js"></script>

The output result is:


Predifined ISO Date Time (YYYY-MM-DD @ HH:MM:SS): – inc/ISODateTimeStamp.js with results below

Requires the following at the location ISO date time stamp is to be used

   <script type="text/javascript" src="inc/ISODateTimeStamp.js"></script>

The output result is:

May be useful as: Our flight home will be,


It is worth noting here that virtually all calendars we have start with Sunday as the first day of the week, based on Judeo-Christian interpretation. The ISO calendar starts the week on Monday. The debate may rage and standards may change but some say He rested on the seventh day. Some would argue that we work and toil for 5-6 days and Sunday (the seventh day) is the day of rest, the day we give to the Lord. Some give Saturday while others dedicate Thursday to their creator.
