3D Wooden Mechanical Perpetual Calendar – DIY Gear‑Driven Date Display (Years 2017–2044)

Keep time in timeless style with the 3D Wooden Mechanical Perpetual Calendar, a functional showpiece that turns date‑tracking into an art form.

Laser‑cut from eco‑friendly wood, each precision‑fit piece slots together in a satisfying self‑assembly experience — no glue, no batteries, just classic mortise‑and‑tenon joinery. The layered rings, adorned with months, days, and years, are connected through a gear‑driven mechanism that glides smoothly with each adjustment.

Once assembled, simply rotate the gears to set the current date, and watch as the mechanical system aligns the calendar’s outer, middle, and inner rings in perfect harmony. Covering years 2017–2044, it’s equally at home as a desk companion, workshop centerpiece, or conversation‑starting gift.

With its intricate etchings and kinetic functionality, the Perpetual Calendar is more than a tool — it’s an heirloom‑quality fusion of engineering and décor.
