Polar Explorer's Day is observed in Russia every May 21, commemorating the anniversary of the establishment of North Pole-1, the first Soviet manned drifting station in the Arctic Ocean, which began operations in 1937. This professional holiday was officially established by a Presidential Decree in 2013, following an initiative by Artur Chilingarov, a member of the Federation Council, and received support from President Vladimir Putin. The holiday celebrates the achievements of polar explorers, particularly highlighting the contributions of the North Pole-1 expedition, which was led by Ivan Papanin and included notable scientists such as geophysicist Evgeny Fedorov and hydrobiologist Pyotr Shirshov. During its operation, North Pole-1 drifted 2,850 km over nine months, marking a significant milestone in polar research. The day is recognized as a tribute to the bravery and dedication of those who explore the challenging Arctic environment.
