Lemniscate Clock

The Lemniscate Clock is an astronomical clock that displays

• sunrise, sunset, true noon,

• moonrise, moonset and moon phase

on an analogue lemniscate-shaped dial.

More features are:

• App, wallpaper and widget.

• Extensive customizing options or a gallery for quick selection.

• 24-hour clock with a unique dial.

• Load, save and share your clock design.

• Battery-friendly implementation.

• Lemniscate Clock remains visible when the device is connected to the charger.

• No network needed, everything is calculated locally.

The top loop shows the daytime hours and the bottom loop shows the nighttime hours. The size of the loops varies depending on the season. The day loop is larger than the night loop in summer and vice versa in winter. Sunrise and sunset lie on the intersection of the loops.

Any time and date can be simulated by swiping across the screen. Swipe the top half of the screen to change the time and the bottom half of the screen to change the date. In this way the cosmic rhythms and relationships of the sun at any hour and day of the year can be discovered and studied for any place in the world. This simulation can also run automatically as an animation.
