The first round of the Egyptian presidential elections will be held March 26-28 and the run-off on April 24-26.
Incumbent Abdel Fattah Al-Sisi has not yet said whether he will run for reelection but for the moment there are no candidates that could challenge him successfully.
The independent NEC, established by a presidential decree in August 2017, is a 10-member commission and has sole responsibility for supervising general elections and referendums in Egypt.
A pro-Sisi campaign said in late December that it collected over 12 million signatures of Egyptians, more than 11 percent of the population, supporting Sisi to run for a second presidential term.
First-round results of the election in March will be announced on 2 April and, in the event of a run-off, on 1 May.
"I have seen that I will not be the ideal person to lead the state's affairs during the coming period".
Egyptian rights and opposition lawyer Khaled Ali announced in November his intention to join the 2018 presidential race.
However, he announced on Sunday his final decision not to run for the presidential elections.
Elections for voters outside the country will be held between March 16 to 18.
It will be Egypt's third election since the 2011 uprising which ended strongman Hosni Mubarak's long rule.
In November, former Egyptian Prime Minister Ahmed Shafiq also announced his intention to return from the United Arab Emirates, where he had resided since 2012, in order to run in the 2018 Egyptian elections.
