/* JavaScript to automatically update
a calendar facility on a web page

/*

An example of using my code is to write in the HTMl:

<script> 
<!--
event(1,1,2,5,"YOur Calendar Event Here");
-->
</script>

This will output "Your Calendar Event Here", from he 1st of Jan
until the 2nd May. 

The output is formatted to give a line before and after the inputed text.

event_year is the same, expect that you woudl write:

event_year(1,1,2006,2,5,2006,"YOur Calendar Event Here");

to get the event to only be used in 2006. 

If the year is the same for both inputs, then the funcation is the same as
event, (after a few checks, event is called).

Here are the function callings explained a bit more.

event(start day of the month, start month, end day of the month, end month, "The text in speach marks");
event_year(start day of the month, start month, start year, end day of the month, end month, end year, "The text in speach marks");

**************************************************
Remember to put a semi-colon - ; - after each line!
