A New Form of Time - Centenary Clock App

Modern clocks are built using the sexagesimal system, a relic of the Mesopotamian civilization around 3000 BC.
However, in today's digital society, sexagesimal systems can be difficult to use intuitively, making calculations particularly challenging for children.

This app therefore uses a centenary clock, more suited to the digital age.

One hour is made up of 100 minutes, and one minute is made up of 100 seconds.
The simplified division of numbers allows anyone to intuitively manage time.

The clock cannot be displayed on the home (lock) screen on devices that do not support live wallpapers. Please use the widget.

=====================================

✅ Benefits of a Centennial Clock

◆ Easy to Calculate - Calculate Time with Written Calculation ◆

Because the centennial system is composed of multiples of 10,
addition, subtraction, division, and other operations can be calculated using standard written calculations.
Everyday calculations like "What time is 15 minutes from now?" can be done quickly,
making it easy for even children with math difficulties to understand intuitively.

◆ Experimental Results: Calculation Speed ​​Increased by 2.5 Times ◆

Compared to the sexagesimal system, calculations are simpler,
and experiments have shown that time calculation speed increases by approximately 2.5 times.
The more you get used to it, the more comfortable you'll be with time.

◆ Excellent compatibility with the digital world ◆

Devices, apps, and data processing are based on a decimal system.
Decimal time naturally blends with digital displays,
and is easy to use as a new "sense of time" in the digital age.

===================================

What is decimal time?

1 day = 24 hours (as before)
* 1 hour = 100 minutes
* 1 minute = 100 seconds

These are simple rules.

For example,
"1 hour 40 minutes" or "3 hours 75 minutes" are all in units of 100, making them easy for anyone to understand.
[Centenary Clock]
・ 1 day = 24 hours
・ 1 hour = 100 minutes
・ 1 minute = 100 seconds
