Abstract

The aim of this study is to improve the static equation of the possibility of seeing the crescent.
The factors (age of the moon, moon altitude, anomaly of the sun, the duration of stay Crescent (mukth)) for
many years from (2004 to 2013 A.D) has been calculated and used to improve the equation of the probability
of sighting the crescent. We find through the analysis of these factors and compared with different astronomical
criteria's that the results we obtained were more accurate and in a good agreement with other criteria.
