Secular holiday : The fighting of WWII tn Europe ended on May 2nd, 1945. The surrender of German troops was signed on May 4th and 5th but officially the war ended at midnight on May 8th 1945. To remember this important event, the Russians created a national holiday called Victory Day which is celebrated on May 9th in Russia. Russia mainly fought a war to defend itself, which is called a "patriotic war". In Russia almost all the families have at least one person who took part in the war. The other old citizens who did not fight during the war had to work in factories to make guns and preparations, which wasn't easier than fighting. They too are honored on Victory Day.
The main reason for the celebration of Victory Day was to remember the people who died in the war. On that day, flowers are laid on their graves and veterans that are still alive go out on the streets wearing their medals and orders. There are few of them left now days and the number is getting smaller every year.
work on weekends and non-working holidays is not overtime work.
