Investor calendar for stocktraders

Hi,
Basically i am looking for financial calendar that shows most important events that will happen in the world.
Particularly in States as it normally affects the rest of the market.

eg: yesterday FED reserve cut an interest rate which lead stocks to soar.
is there investor calendars with those and similar dates?
eg: fed reserve cuts, important financial reports estimates, US unemployment rates or any other events that might affect global markets.

google showed this:
http://www.nationalmortgagenews.com/calendar/ (not advanced)
http://biz.yahoo.com/c/e.html (looks like useless as it doesn't include fed reserve data)

anyone knows a better investor calendar in the web?

I just spotted this- I recommend http://www.forexfactory.com (www.forexfactory.com) for global calendar etc.

I'm personally looking for one specifically relating to Irish stocks -
Annual/interim results, AGMs, Ex-div, etc
can anyone help?
