For Earth to make one complete revolution around the Sun takes 365.24 days. This amount of time is the definition of one year.
Effects of Revolution of the Earth: Certain areas are tipped towards, or away from, the sun at different times of the year. This tilting causes the four seasons of the year. The tilting also creates opposite seasons in the Northern and Southern Hemispheres.
The British conquered Myanmar, and the French conquered Laos, Cambodia, and Vietnam in the the 1800's and 1900's, and the conquerors always leave some of their culture behind. Hope this helps. Good luck!
