Crumbs! Why can't every day be Saturday?

Judy Moody is Monday-morning mopey. Another week in her same-old seat at her same-old desk in her same-old school. Even worse, there aren't any days off from school for ages. But when she steps into Class 3T, Judy's Monday frown turns upside down. Pop! Pop! Pop-pop-pop! Mr. Todd is making Monday special by celebrating Bubble Wrap Appreciation Day (no lie)! This gives Judy an idea that just-might-maybe turn her week around: why not make every day of the week a holiday? But after she and her friends come up with a week's worth of wacky celebrations, from feeding ninja squirrels to honoring National Sneak Some Zucchini Onto Your Neighbor's Porch Day, will the weekend be one big letdown?
