When to Observe ?

The geocentric new Moon will occur on Tuesday 07 December 1999, at 22:32 UT. On this day (Tuesday 07 December), the crescent will not be possible to be seen from anywhere on Earth! While on Wednesday 08 December The program Moon Calculator by Dr. Monzur Ahmed -according to Yallop criterion- showed that the crescent will be visible by telescopes starting from Egypt, while it should be visible by naked eyes somewhere starting from the Atlantic Ocean. And so, countries west of these areas (within the parabola) should be able to see the crescent on this day (08 December). On the other hand, countries outside the parabola will see the crescent on the next day (09 December). Consequently, arrange to observe the crescent after the sunset of 08 or 09 December. Kindly click on the below icon to see the visibility parabola as plotted by the program Moon Calculator

In other words, the correct beginning for Ramadan 1420 AH (according to the actual sighting of the crescent), should be on 09 December for countries within the above parabola, while other countries should start fasting on 10 December. However, Saudi will start Ramadan either on 08 or 09 December, because 29 Sha'ban in Saudi will be on 07 December! The reason for this problem is because Saudi did NOT start Sha'ban according to the actual sighting of the crescent! However, it is quit unexpected that Saudi will start Ramadan on 08 December. We think that most countries will start Ramadan on 09 December.

Results of seeing the crescent, and the first day of Ramadan in different countries will be added here 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.
