The Secretary General of the Organization of the Islamic Conference (OIC) has called upon the Islamic world to follow a unified Hijri calendar. While extending Eid greetings to Muslims worldwide, Ekmeleddine Ihsanoglu, the secretary general, said the different dates at which the Islamic world celebrates this happy occasion does not reflect the aspired unity on such a blessed event, but is rather an indication of dispersion and disunity and creates confusion in the public opinion. He said it was uninspiring at a time when scientific and technological progress has made it so easy to determine the dates of our religious occasions that are meant to unite all Muslims.
