On Monday April 4, 2011 the new moon was sighted from Israel. The moon was first sighted from Mount Hezekiah at 7:28 pm by Nehemia Gordon and at 7:29 pm by Yoel Halevi. The moon was also sighted from Ashdod by Magdi Shamuel at 7:40 pm. (The moon should be sighted from Jerusalem).
Again: The Biblical first Crescent of the moon was sighted on Monday evening April 4th 2011. It was first sighted at 7:28 P.M. by Nehemia Gordon followed shortly thereafter by Yoel Halevi, = 2 or more Witnesses.
For all Nations "West" of Jerusalem, (including all of the USA)"up to" man's false Date Line:
But the Kiddish is on Tuesday Evening April 5th 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 Tuesday night April 5th (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, Wednesday April 6th Daylight portion is day 1 of Aviv because West of the Date Line you have to wait until Tuesday evening April 5th to start Yah's month.
In summation:
"Daytime" Wednesday April 6th is day 1 of Aviv for all Nations "West" of man's false International Date Line.
Therefore day 1 of Aviv starts on the evening of April 5 (Tuesday evening) "West" of man's false International Date Line.
