Snapshot time and continuous time

I’m working on a perpetual lunar calendar and playing with ideas on how to visualize time. While sketching I was reminded of this funny thing about how we visualize time. Digital clocks are about this moment. They tell “snapshot time.” While analog clocks point to a moment but in a larger context, a 12 hour cycle. They tell “continuous time.”

Extending this distinction to perpetual calendars, the ones that hide most of the back plate and show only today’s date through a tiny window are telling snapshot time. It’s Saturday 24 November and that’s what time it is right now.

But the value of using a lunar calendar isn’t in knowing what moon phase we’re in right now. The value is in being aware of where we have been and where we are going. Something like an analog clock is a better visual for this.
