Harley Davidson 100th Anniversary 50 Year Perpetual Calendar Disk / Dial

Description: You're looking at a 50‑year perpetual calendar disk made for the 100th Anniversary of Harley Davidson Motorcycles. Made of metal as a novelty paperweight or as a collector’s item. This device uses rotating discs to align the year and month, allowing you to read off the weekday for any date within a 50‑year span (in this case, 2003–2052)

Here’s how it works:

• Rotate the inner disk so that your desired year from 2003 to 2052 aligns under the month.
• The day‑of‑week calendar at the bottom then shows which weekday corresponds to a particular date that month.
• Special markings in red indicate February and January for leap years.

These calendars follow the Julian/Gregorian perpetual calendar concept, where 14 yearly calendar layouts (7 common‑year and 7 leap‑year types) are mapped to a range of years based on weekday cycles

Year: 2003

Condition: New Old Stock. Comes in a 100th Anniversary clamshell style metal box. A must have for any collection.
