According to the Universal Hejric Calendar (UHC), which is based on the calculated crescent visibility, the start of this month in the Eastern Region will be on Thursday 13 September 2007, and in the Western Region will be on Thursday 13 September 2007 also.
- Results of seeing the crescent, and the first day of the month in different countries will be added here Inshalla as we receive the reports from ICOP's members. If you wish to be a member in ICOP, or to know more about it, kindly click here.

Crescent first observation through 15x80 binoculars by Alireza Mehrani:
Crescent final observation through 15x80 binoculars by Alireza Mehrani:
Observer: Alireza Mehrani
Two years ago, I saw the crescent of Dhul-Qi'dah 1426 (December 2, 2005) in the same location. Although, this year, the crescent of Ramadan was very similar to the 1426 Dhul-Qi'dah crescent, but it was thinner and also 0.5° altitude less at the sunset.
By a theodolite camera, I found the crescent situation at 18:05 LT, and waited for the observation time. At 18:05 I started the observation and every 5 minutes by the theodolite, I was controlling the crescent direction. From 18:05 to 18:22, I saw a flash in the view field. For some seconds it repeated but without any fixed image. I couldn't be satisfied that I have observed the crescent. It seemed to be a curved, but because of the very appearance, I changed my mind for observing and it disappeared.
The crescent had mixed in the thin dust. It was just some seconds after 18:22, that I recognized a flash again in the view field center. After some seconds, the mentioned flash became a clear and permanent image from a thin short arc. The image started flashing but it became fix again for a longer time. I became sure that this arc is the crescent and so surprised became of the arc length shortness.
When the crescent started flashing, I couldn't see it any more. Although I continued the observation until the crescent sinked in the middle part of the thick dust, but it was futile.
Note From ICOP: This is very important picture, because this observation holds the minimum lag-time for seen crescent, that is 20 minutes. Using Accurate Times, we have the following information about this crescent:-
- Topocentric Moon Age: 25 Hours and 02 Minutes
Note from ICOP: Kindly notice that the observer was NOT able to see the crescent even through telescope! The crescent was ONLY captured using a CCD camera, but it was NOT seen even through a telescope. Dr. Peter added later on:
"Location was: +44.01 latitude, 05.50.51 East, longitude, Southern France, 568m altitude.

Surprisingly, Saudi announced officially on Saturday 08 September 2007 that they are not sure of the beginning of both; Rajab and Shaban, and hence they will look for Ramadan crescent on Monday 10 September!! So Ramadan could start in Saudi on Tuesday 11 September!! We wonder how they will look for the crescent on Monday, when it is impossible to be seen on Tuesday, and it will NOT be seen by naked eyes from Saudi even on Wednesday!!
