Statistician's Day is observed in Ukraine every December 5. This professional day was established by President Leonid Kuchma in 2002, with the first celebrations occurring shortly after the decree was signed on December 2 of that year. The date commemorates the anniversary of the first Ukrainian Census, which took place in 2001 and marked a significant statistical event for the country following its independence from the Soviet Union in 1991. The holiday is primarily recognized by professionals in the field of Ukrainian statistics, who celebrate by following corporate traditions and receiving congratulations from family and friends. While there are no national festivities, many workers participate in corporate parties to mark the occasion.
