Look at your desk, and the objects on it. Is there anything there that you think will still be in production in 60 years?

Legendary Italian industrial designer Enzo Mari first designed the Formosa perpetual calendar in 1963. Produced by Italian design label Danese Milano, it consisted of a simple aluminum plate and a series of lithographed PVC cards printed with red or black Helvetica characters.

In 1967 Mari followed up with his Timor, a tabletop variant. The cards were still PVC, but the new base was made of ABS. If you worked in a dusty office and needed to clean the calendar, the whole thing could be rinsed off in a sink.

Both calendars were enduring hits, and today Danese Milano still has both in production.

Obviously Mari didn't have the calendars indicate the year. I wonder if he could have imagined they'd be used to keep dates in 2024.

Sadly Mari, at 88, died of COVID during the pandemic in 2020.
