A procession will be held in the capital, Abuja, with 219 girls taking part to represent each missing girl.
The abduction of the girls in Chibok in north-eastern Nigeria sparked global outrage, with nations such as the US and China promising to help find them.
There have been reported sightings of the girls, but none has been found.
Boko Haram say the girls have converted to Islam and been married off. One witness said she saw more than 50 of them alive three weeks ago in the north-eastern town of Gwoza. It has been a whole year of agony for the relatives of the missing 219 Chibok girls. There have been a few sightings of some of the abducted students but very little official information from a government that has long promised to rescue them from the clutches of Boko Haram.
Nigeria's incoming president, Muhammadu Buhari, has promised to "crush" the insurgents and said his government would "do everything in its power to bring them home".
However, he added: "As much as I wish to, I cannot promise that we can find them."
