The Egyptian army has begun clearing demonstrators and the media from outside Cairo's presidential palace.
It follows violent overnight clashes between supporters and opponents of President Mohammed Morsi that left five people dead and 644 injured.
Most protesters left the area by the 15:00 (13:00 GMT) deadline, though some opposition activists remained.
Meanwhile, Egypt's top Islamic body has called on the president to suspend his decree claiming sweeping powers.
The Al-Azhar institution also demanded an unconditional dialogue between the president and his opponents.
The BBC's Jon Leyne in Cairo says this move by one of the most respected bodies in Sunni Islam has put President Morsi - who was largely brought to power by the powerful Islamist Muslim Brotherhood - under more pressure.
