This is a special purpose clock that displays Days Left until a date.

You set the number of days after setting the time.

It can also be used as a large format 12 hour or 24 hour clock, as shown in the lower right photo.

A high precision temperature compensated oscillator gives 2 minutes per year accuracy, and a 1 hour backup capacitor give power outage protection.
