On what date, your Independence day comes????

Hello, kanukrishna! I am from Romania, and our Independence Day is on May the 9th. Romania (at that time comprising only Wallachia and Moldavia) gained its independence from the Ottoman Empire on May the 9th 1877. The Romanian entered the war between the Russian Empire and the Ottomans alongside Russia, with the condition that if they emerge victorious, Romania will remain independent. The Russians were granted free passage through Romania and the Romanian Army joined them in battle. The Independence was paid in blood. The Romanian soldiers freed the fortified points of Rahova, Plevna and Grivita (now in Bulgaria) in heroic attacks still remembered in poems and stories. The Russians kept their word, as the agreement was made in a moment when they really needed reinforcement from Romania. The Independence Day is not, however, our National Day. The National Day of Romania is celebrated on December the 1st, the day when in 1918 Romania became a whole, gaining back two more territories, Ardeal (occupied by the Austro-Hungarian Empire) and Basarabia (occupied by the Russian Empire; now Basarabia is an independent country - Moldova).
