The geocentric new Moon will occur Inshalla on Thursday (02 January 2003), at
20:23 UT. On this day (Thursday 02 January 2003), it is not possible to see the crescent from anywhere on Earth. While on the next day (Friday 03 January 2003) the program Moon Calculator
by Dr. Monzur Ahmed -according to Yallop criterion- showed that it is possible to see the crescent by optical aid from the Indian Ocean, Southern Saudi, and Northern USA, while it could be seen by naked eyes from Southern Africa, Southern USA, Central America and Southern America. Thus, according to the actual sighting of the crescent, the start of Thul Kea'dah should be on Saturday (04 January 2003) is most parts of the world or on (Sunday 05 January 2003) in the eastern countries.
