The Senior Special Assistant to the President on National Assembly matters (Senate), Senator Ita Enang, made the disclosure to newsmen after the signing ceremony.
The new law allows public holiday to be declared on June 12.
Henceforth, May 29th will no longer be public holiday but handing over date and working day.
Until 2019, the date was celebrated as the Democracy Day because it was significant in Nigerian history as it was on May 29, 1999, Nigerian military handed over to former president Olusegun Obasanjo.
But president Muhammadu Buhari changed the Democracy Day to June 12 in memory of the politician and business man, late MKO Abiola, the winner of June 12, 1993 presidential election, which was adjudged most free and fair Nigerian election but nullified by the military dictator Gen. Ibrahim Babangida junta.
Meanwhile, Wednesday has been declared public holiday by the federal government.
