Polar Clock

How to read it

Point at a step, or tap it, to light up that part of the clock.

1. 1

   Each ring is one unit, from the outside in: seconds, minutes, hours, day of the month and month of the year.

2. 2

   Arcs grow clockwise starting from 12 o'clock.

3. 3

   When an arc closes into a full circle, its cycle is complete and it starts again from zero.

4. 4

   The outer green ring shows the seconds in the app; the widget leaves it out.
