Help me choose a better background for my image

Hey everyone,

My web designer made a design showing the public holidays, but I didn't like the background of the image. The page on which the image will take place does not look very harmonious in my opinion.

Could you recommend a background that will fit the page better? The table will remain the same.

Here’s the image and the web page that the image will be located.

Image: (sorry it's in Turkish, the image shows the national holidays in Turkey)...
