All of you may have heard about the google calendars . Its a free service by google. You just need a gmail id .

But I was looking like a one that's freely available. Now adays I got  a chance to work with the javascript frameworks like jquery and prototype. Working on it, I was impressed . Its really cool guys, if you know little javascript then , you can look into it . Yes once you used , you will never go without using one of it . :) .
