Tibaldo and the Hole in the Calendar

Reach for this book when your child is grappling with a sense of injustice caused by rules that seem arbitrary or when they feel like their personal identity is being overlooked by 'the system.' This historical novel follows Tibaldo, an eleven year old boy in 16th century Italy who discovers that the transition from the Julian to the Gregorian calendar will effectively erase his birthday. It is a brilliant entry point for children who are naturally curious about how the world is organized and why certain 'facts' like time and dates exist the same way for everyone. While the premise sounds like a math problem, the heart of the story is Tibaldo's emotional journey. He experiences genuine anger and a sense of loss, leading him to seek out the great minds of his time to find a solution. For parents, this is a unique tool to bridge the gap between STEM concepts (astronomy and mathematics) and social-emotional development. It is perfectly suited for independent readers aged 8 to 12 or as a family read-aloud that will spark deep questions about science, religion, and the meaning of fairness.
