Search for all videos created on a Saturday

I am using **Linux Mint**. There are several years worth of files and folders scattered everywhere. My goal is to find a way to search my entire hard drive for any **video files** that were **created on a Saturday**, I do not know the date in number format. I do not know the file name, nor the file extension, but they were certainly videos. I am preferably looking for a GUI program where I can see a thumbnail of the video file, to save me from having to manually open each one. But, failing that a command line solution is also okay.
