Javascript Sharable, Bookmarkable, Group Calendar

Bookmarkable, Sharable Group Month Calendar

(Year)

Big textbox takes |-separated (| is vertical bar) list of day events in the following format you wish to mark off:
daynumlist="event string"
prioritystring:daynumlist="event string" (optional priority)
where daynumlist consists of a comma(,) separated list of day numbers or day number ranges in the form daynum-daynum
When multiple events have days that collide, this program will concatenate/merge/string together the events of each individual day separated by a semicolon (;). the priorityword can be a number, it's just a string,I think it can even have spaces.
Example:
12,18,20-21="Bowling@Al's Alley"|Mandatory:20="Board Mtg@Green Rm"|17-22="Parachuting at Dave's Airport"|2="Mark's Wedding"|15-17="camp"|27="Joe's Bday"|10-12="Singles Conference"
Rules: it cannot have leading or trailing spaces, newlines, or tabs or HTML.

result is a bookmarkable URL Group Calendar which you can email and share with others via google groups, etc., no account required for this page.
