Chairman of the committee Mufti Munib-ur-Rehman presided over the meeting.
The moon was sighted in various parts of the country, including Lower Dir, Buner, Nathiagali, Abottabad, Quetta, among others.
Millions of Muslims across the world are marking the first day of holy month of Ramazan.
The PMD on May 4 had issued a handout stating that there are fair chances for the moon to be sighted on May 16 evening. Scores of Islamic faithful usually commemorate the month-long period with dawn-to-dusk fasting and prayers. The premier observed that the holy month is an opportunity for introspection.
He added the age of the new moon on Wednesday evening will be more than 26 hours in all cities of Pakistan, and the difference between sunset and moonset will be 58-60 minutes.
Therefore, the first Fast will be observed on Thursday (May 17, 2018) in Pakistan, India, Saud Arabia, United Arab Emirates (UAE), Oman, England, Indonesia, Malaysia, Singapore, Brunei, Japan, and Australia among others.
Apart from Saudi Arabia, Muslims will start observing Ramazan in Malaysia, Australia, England, Japan, UAE, Gulf nations, USA and other countries across the globe on Thursday.
Tradition holds that it was during Ramazan that the Prophet Mohammed started receiving revelations of the Muslim holy book, the Koran.
