President Mahmud Ahmadinejad has promised to announce "good news" about advances in the country's nuclear program during the festivities.
Iran says its nuclear program is peaceful, but Western critics have accused Tehran of secretly trying to develop nuclear weapons.
In December, the UN Security Council adopted limited sanctions against Iran aimed at curbing its nuclear program.

But he added that "the Islamic ummah...can break the domination of the West with its unity."
February 1979 marked the return to Iran of the exiled Ayatollah Ruhollah Khomeini, the father of the country's Islamic Revolution.
The "Ten Days Of Dawn" conclude on February 11.
