The Central Ruet-e-Hilal Committee will meet on Thursday evening in Karachi for Shawal moon sighting.
The end of Islamic holy month of Ramadan is marked by the key Muslism festival of Eid al-Fitr, in which Muslim families gather for the "feast of breaking the fast".
Earlier today, the Knowledge and Human Development Authority that all schools will also be closed from this Thursday, until Sunday, with the possibility of the holiday extending to Monday also.
He congratulated the Muslim faithful on the successful completion of the Ramadan.
The exact date of Eid depends on a combination of the sighting of the new moon and astronomical calculations. However, the number of days in the month is only established after sighting of the moon.
Eid-ul-Fitr, however, has a particular Salat (Islamic prayer) of two units generally offered in an open field or large hall which may be performed only in congregation (Jamm'at).
Eid is expected to begin on either Friday, June 15, or Saturday, June 16. People from across the world try to sight the moon after sunset (when they break the fast) on 29th Ramzan. A moon-sighting committee has been drafted for this objective.
But if the new moon is not seen by the committee on Thursday, Friday will be assumed as Ramadan 30 and Eid Al Fitr will begin on Saturday.
