This Mom Clock calendar page is built to work like a modern utility tool: a clean yearly overview, clear month transitions, and holiday context without turning into a cluttered portal. It is server-rendered for reliable indexing and fast loading, while the control bar adds live local time and quick route switching.
The data layer already supports country-based holidays and keeps a placeholder field for future moon phase data, so we can grow this calendar system without rebuilding its structure later.
