It was not immediately clear whether either side was observing the ceasefire, even with world leaders -- including China's Xi Jinping, Brazil's Luiz Inacio Lula da Silva and Serbia's Aleksandar Vucic -- in Moscow for commemorations of the end of World War II.
US President Donald Trump has sought to end Moscow's three-year military assault on Ukraine since his inauguration in January, but has failed to ease hostilities between the enemies.
The Kremlin has said Russian forces will honour Putin's order for the duration of the holiday, but will respond “immediately” if Ukraine launches any fire.
“We are not withdrawing this proposal, which could give diplomacy a chance. But the world is not seeing any response from Russia,“ he said.
Putin announced the truce last month as a “humanitarian” gesture, following pressure from the United States to halt his three-year assault on Ukraine.
Ukraine has said it does not believe Russia will adhere to this truce and accused Moscow of hundreds of violations during a previous, 30-hour ceasefire ordered by Putin for Easter.
The White House has become increasingly frustrated at the lack of progress towards a peace deal between the warring sides, despite US President Donald Trump's efforts.
'Peaceful atmosphere'
More than 20 world leaders were expected in Moscow for the May 9 parade.
He also said authorities had jammed internet connections ahead of the parade, citing the threat from Kyiv.
“As long as guests are here, until May 10, we need to be ready for restrictions,“ he added, calling on Muscovites to be understanding.
'Nothing scares us'
“We are from Rostov-on-Don. Nothing scares us,“ said 22-year-old student Valeria Pavlova. The southern city serves as a command and logistics hub for the Ukraine offensive and has regularly been targeted.
But scenes at airports in Moscow, Saint Petersburg and other cities were more chaotic.
Kyiv's drone attacks disrupted some 350 flights Tuesday and Wednesday, Russia's Association of Tour Operators said. Social media videos showed people sleeping on the floor and airports with rows of over a dozen planes queueing on the tarmac.
Ukraine's airspace has been forced to close since Russia launched its offensive in February 2022.
