12:18 UT.
Sighting the new crescent on (Monday 05 May 2008) and on (Tuesday 06 May 2008) is shown in the below graphs using the program Accurate Times by Mohammad Odeh according to Odeh criterion. Where:-
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 Tuesday 06 May 20088, and in the Western Region will be on Tuesday 06 May 2008 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.
So far, the earliest sighting of the crescent -after sunset- was on Tuesday 06 May 2008 from Indonesia.

Sunday 04 May 2008:
This observation was anything but trivial. I wanted to use my technique for pinpointing the location of the crescent despite the prediction of a naked eye crescent - for practice, and to look for ways of improving the technique. It turns out that I needed the technique.
There were intermittent clouds all along the eastern horizon, well up into the sky. However, my plans worked well (except for not getting a limiting magnitude), and I was pointed at the correct location an hour before the Moon would rise above Pusch Ridge.
When the time came, I was on a cloud, but engaging the clock drive, and following the invisible Moon for ten minutes brought it to a break, and the crescent was visible. However, it was too tenuous to be seen in the finder scope, let alone with the naked eye. I followed it for 41 minutes, and the image became less and less distinct. I wasn't able to measure the extent of the crescent with any precision. This was through several deep blue breaks in the clouds. At 06:13 a.m. (local) the crescent faded from view in a clear part of the sky - before the sun rose over Pusch Ridge.
The significance of all of this? Ever since failing to see crescents which were 20-some hours from new, while easily observing them about 17 hours from new, when other conditions like altitude, atmosphere, and elongation were similar, I have considered it a mystery. I usually attributed that mystery to looking in the wrong place, being out of focus, or observing through inconspicuous weather problems. However, I was never fully satisfied with any of those explanations. Yesterday's observation has given me a hypothesis that I have long been considering.
I believe that the reflectance for the edge of the Moon that we are seeking when observing the crescent varies considerably, and this reflectance is more determinant with respect to visibility than the calculated width of the crescent or the calculated percent illuminated. Furthermore, I suspect that the range in this effect is significant enough to become a greater factor in observability than clear sky atmospherics. Finally, I believe that we have a good enough understanding of the Moon's topography, geology, and libration to be able to predict the reflectance.

"On my request, today i.e. on May 6, 2008(Tuesday, 29 Rabee-uth-thani 1429 in Pakistan), many members of personal moon sighting committees of our institute "JAMIA-TUR-RASHEED" and my many friends tried to sight the moon all over the Pakistan and they easily sighted the moon, as it was expected tonight that moon could be easily sighted in Pakistan and mostly populated world. Reporters are as follows:
1. Maulana Noor Wahid Shah + one person (Madrasah Islamiah "a branch of JAMIA-TUR-RASHEED'' Battal, N.W.F.P. sky was partially cloudy.) He was the first person who reported me and the official moon sighting committee of Pakistan at 19:20 LT.
2. Maulana Abdul-Qahhar (Pishin, Baluchistan. sky was partially cloudy)
3. Maulana Abdul-Hakeem (Texela, Punjab. sky was clear)
4. Maulana Rustam + 2 persons (Hango, N.W.F.P. SKY was partially cloudy)
5. Maulana Faisal + Maulana Shahbaz + 20 ulama (Gaddi Bhit, Mitthi, Sindh, sky was very cloudy) Maulana Faisal sighted the moon first at 19:10 LT
6. Raees Khan + 8 people c/o molvi adnan shahzad (Swabi, N.W.F.P.)
7. Maulana Husain + many people (Charsaddah, N.W.F.P.)
8. Manzoor + Shaukat + Imtiaz c/o molvi Samee-ullah (Mansehrah, N.W.F.P.)
Note 1: I tried my best with 25 ulama and students to sight the moon in Nazimabad 4, Karachi Pakistan, but we could not sight due to very pollution and clouds. Many people tried in many places of Karachi but they could not sight the moon.
Note 2: Vice Chairman of central official moon sighting committee of Pakistan told me on my personal mobile number that he has received the positive reports of moon sighting from many cities of Pakistan; therefore he has officially announced that 1st Jumadal-oola 1429 will be on Wednesday, 7 May 2008 in Pakistan after ending the 29 days of Rabee-uth-thani 1429."

"I hadn't planned to observe this event, considering it to be trivial. Then Roger Sinnott published a piece about the time interval between opposing Moons. I thought that maybe I could follow the old crescent several hours into the day and then by observing Monday's new Moon crescent, break my old record of 33 hours 9 minutes, obtained 21 January 1996.
