WHAT YEAR IS IT ANYWAY?

I was talking to a friend today about the errors in both the Hebrew and Gregorian Calendars,and thanks to another friend Tom Kovach @ www.tomkovach.us who happened to send me an email with the following information I am able to add this to my calculations.
Why is it so important to know "what day"it is?
Or for that matter what "year"it is.
To us in the U.S it's 2009
To the Hebrew it's 5770
But... to the Mason it's different yet!
and it depends which masonic lodge you belong to.
To those in the ancient craft....6009
To those in the A:A:S: Rite 5769
To the Royal Arch Mason 2539
To those in the Royal and Select Masters 3009
To the Knights Templar 891
And to the Order of the High Priesthood 3848

So you might ask,Why is this of any importance?
Say for instance you had an appointment on a given date,in a pre- ordained year
and the clock had been intentionally set so that IT was incorrect,how would you know when to be ready to leave?
Do you think you might be late ?Or that your chariot might come and go before you ever knew that it arrived?

WHICH CALENDER IS RIGHT?
WHAT CALENDER DOES GOD OPERATE ON?
ARE YOU READY?
