On Thursday June 2nd, 2011 the new moon was sighted from Israel.
and since Yah's month cannot be longer than 30 days, that means that the new month starts tonight the evening of June 2 Thursday for all Countries West of Jerusalem up to the International Date Line, and the evening of Fridat June 3rd for all Countries West of man's false International Date Line.
Again: The Biblical first Crescent of the moon was sighted on Thursday evening June 2nd,
"yet" the Kiddish must be on Friday evening June 3rd 2011 for all Countries "West" of Jerusalem, (including all of the USA)"up to" man's false Date Line:

after
Sundown Thursday evening June
2nd in "your" particular City, (for all Cities
"West" of Jerusalem up to man's wrong/false International Date Line).
But the Kiddish is on Friday Evening June 3rd for all Cities "West" of man's wrong/false International Date Line westward till the shadow of the sun reaches the Euphrates river (which is Yah's/God's boundary line for Israel).
Have a thankful (in gratitude), Kiddish celebration Tonight, in remembrance of the sacrifice of Yeshua.

1.) Must wait until the "next" night = must wait until Friday night June 3rd (after Sundown) to start Yah's/God's Kiddish.
Yahweh's Date Line "is" at the Euphrates (which was Yah's (original) eastern border for Israel Genesis 15:18 Joshua 1:4.)
Therefore the Kiddish is "Tuesday" night in Australia all the way West to Pakistan to Yah's Date Line at the Euphrates.
2.) Again: "West" of the false International Date Line, Saturday June 4 the Daylight portion is day 1 of Sivan 1 because West of the Date Line you have to wait until Friday evening June 3rd to start Yah's month.
In summation:
"Daytime" Thursday June 2nd is day 1 of Sivan for all Nations "West" of man's false International Date Line.
Therefore day 1 of Sivan starts on the evening of Friday June 3rd (Friday evening) "West" of man's false International Date Line,
but Thursday evening June 2nd for all Countries East of man's false Date Line.
