Calculateur

Calculateur tells the usable time ahead, mapping each day to 1000 decimal minutes, counting down. It uses a decimal system, rather than the commonly used modified sexagesimal system.

Using the number 1000 as a reference is precise enough for everyday use and relatable when referring to specific parts of the day. Midnight is 1000 (displayed as “NEW”), noon 500, and teatime 333. Even though it is technically a countdown it is not perceived like that, since checking the time usually happens at a glance, not continuously. The displayed number represents all the time we can still use, before we get another 1000 decimal minutes.

The name Calculateur is the result of brilliant conversations with my friend Léo Marzolf and eating brioche.
