On May 31, President Viktor Yushchenko gave lawmakers another day to pass the legislation after they missed a midnight deadline the day before.
The snap elections are part of a deal reached between Yushchenko and his rival Prime Minister Viktor Yanukovych to end weeks of political instability.
In April, Yushchenko issued decrees dissolving parliament. But in order to enable the Verkhovna Rada to pass the laws needed for early elections, he overturned that decision and allowed the chamber to meet in recent days.

RFE/RL's Ukrainian Service asked people on the streets of Kyiv on April 11 whether the Constitutional Court will be able to determine the constitutionality of the president's decree dissolving parliament.
Oksana, a student from Lutsk:
"Their decision will at any rate be beneficial to one of the political forces."
Oleksandr, a high-school student:
"[The court] will be able to do it, but only if the judges agree upon it."
Alla Asilyevna, a pensioner:
"How can the Constitutional Court solve the problem if there is pressure on it from all sides?"
Ivan Yukhimovich, a pensioner:
"If [Prime Minister Viktor] Yanukovych and [President Viktor]Yushchenko find an agreement, everything will be resolved."
Yuliya, a worker:
"I doubt very much that the judges will agree on anything."
