As well as ceremonies of remembrance, concerts, lectures and awards ceremonies are scheduled with events traditionally centering on the walls of Riga castle where thousands of people light candles.
While November 11 marks Armistice Day at the end of the first world war in 1918 for many countries in Europe, in Latvia conflict raged on and November 11 marks the day of victory in a decisive battle a year later that helped maintain the newly-independent country's unity.
Geenral Raimonds Graube, the country's senior military officer led tributes on LTV saying "It is our duty to remember those who came together for our freedom."
"Today is a celebration day - but it is also a normal working day for our soldiers," Graube added.
You can follow special shows on the LTV national television channel too.
