Egypt's national elections are set for March 26-28, National Election Commission (NEC) head Lasheen Ibrahim announced Monday at a news conference in Cairo.
The announcement comes a day after Egyptian President Abdel Fattah al-Sisi's only serious challenger - former army general and premier Ahmed Shafiq - bowed out of the race, reversing his pledge to challenge the president at the polls.
The founder of the Egyptian Patriotic Movement party narrowly lost a presidential election to the Muslim Brotherhood candidate Mohamed Morsi in 2012 before fleeing for the UAE, where he has lived since.
Results of the first round will be announced on April 2, Ibrahim said.
President El-Sisi has not yet announced if he intends to run for re-election, though others have announced their candidacies, including prominent human rights lawyer Khaled Ali in November 2017.
Egyptians living overseas are to cast their votes on March 16-18, he added, with second round ballots on April 19-21 if necessary.
It will be Egypt's third election since the 2011 uprising which ended strongman Hosni Mubarak's long rule.
"Final results will be announced on May 1", he said.
The last presidential elections were held in 2014 when Sisi was elected to office.
If Ali's conviction is upheld, he will be ineligible to run in the 2018 elections according to Egypt's Presidential Elections Law.
Shafik returned to Egypt from the United Arab Emirates in December after announcing his intention to run, setting off a firestorm of criticism from state-aligned media.
