The curfew being imposed on Egyptian will still be in effect Wednesday, but for fewer hours, according to state television, DPA reported.
The curfew will begin at 5pm (1500GMT) instead of 3pm, and will last until 7am the next morning, instead of 8am.
While there were some reports of efforts to enforce the curfew in certain sensitive areas, by and large Egyptians were able to protest each night without interference from the military.
The curfew was first imposed last Friday.
