📆Manual Calendar Range, 2018–2040: Turn the two calendar wheels to select a year and month, then read the matching date layout. LK201 is a hands-on wooden desk calendar designed for dates from 2018 to 2040. 📆A Manual Calendar, Not an Automatic Device: The display does not move forward daily or update itself. Set the wheels by hand whenever you change the date. 📆Compact Sundial-Style Desk Model: At 175 × 90 × 170 mm when assembled, it is designed as a small wooden object for a desk, study or shelf—not a large or highly complex mechanical challenge. 📆A Finished Object with a Daily Purpose: The double-wheel layout and engraved base turn date-setting into a tactile desk ritual and a thoughtful gift for people who enjoy vintage-inspired objects. 📆For Accurate, Smooth Adjustment: Build on a flat surface, align the calendar wheels carefully and follow the setting steps in the manual. If a wheel feels tight or the date looks incorrect, wax and readjust the moving parts as directed., Manufacturer: ROBOTIME
