On Tuesday, Palestinian groups and Egyptian mediators confirmed that the Cairo-based talks ended in truce.
Palestinians poured into the streets of the war-torn sliver and West Bank to celebrate as the Egyptian-brokered truce took effect at 1600 GMT.
People and traffic filled the streets with drivers honking horns and crowds chanting slogans.
The truce stipulates the removal of Israeli blockade as well as the provision of a guarantee that Palestinian demands will be met.
Crossings between Israel and Gaza will open and the two sides will continue holding indirect talks, according to the deal.
The Palestinian territory's fishing zone will also be widened in the Mediterranean.
The Palestinian resistance movement Hamas said the deal marks a victory for Palestinians and called for mass rallies in the occupied West Bank.
"Today we declare the victory of the resistance, today we declare the victory of Gaza," Hamas spokesman Sami Abu Zuhri said.
Israeli warplanes and tanks started pounding the blockaded enclave in early July, inflicting heavy losses on the Palestinian land.
Some 2,139 Palestinians, mostly civilians, including women, children and the elderly, were killed in 50 days of the Israeli onslaught on Gaza. Around 11,000 others were injured.
Tel Aviv says 69 Israelis have been killed in the conflict, but Hamas puts the number at more than 150.
