“The Ancient Egyptian civilization is usually credited with establishing the division of the night into 12 parts, although there were many variations over the centuries. Astronomers in the Middle Kingdom (9th and 10th Dynasties) observed a set of 36 decan stars throughout the year. These star tables have been found on the lids of coffins of the period. The heliacal rising of the next decan star marked the start of a new civil week, which was then 10 days. The period from sunset to sunrise was marked by 18 decan stars. Three of these were assigned to each of the two twilight periods, so the period of total darkness was marked by the remaining 12 decan stars, resulting in the 12 divisions of the night. The time between the appearance of each of these decan stars over the horizon during the night would have been about 40 modern minutes. During the New Kingdom, the system was simplified, using a set of 24 stars, 12 of which marked the passage of the night.” (wikipedia)
If this makes perfect sense to you, don’t bother downloading our clock. However, if you want a simpler approach to the division of time (the day in this case) feel free to try our ProgressClock™. This clock simplifies time by showing the elapsed percent of the day. Unfortunately, a quick Google search revealed that this has been done before, but we took it a step further by making it a Google Gadget which you can add to your iGoogle page. If you guys like this, we might also make a Vista widget, Java applet, etc.
