Shachihata Number Stamp | Perpetual Calendar

The Connected Number Stamp – Perpetual Calendar by Shachihata is a modular stamping system designed to create customizable calendar layouts in planners, journals, and notebooks.

Instead of using a fixed date stamp, this set includes individual stamp blocks for each day of the week and each date, allowing you to assemble a calendar in any format that fits your page. The pieces snap together horizontally or vertically, so you can arrange them to build monthly grids, numbered columns, or custom layouts.

Because the system is perpetual, it can be reused every month and every year—simply rearrange the stamps to match the calendar you need.
