How ancient timekeeping mechanism looks in modern times
I have always been fascinated with ancient timekeeping mechanism and how it looks in current times e.g. in Hours, minutes and seconds. We calculate 1 day = 24 hours. Here's how ancient people break 24 hours into sub units: 1 Day = 8 Pehars. 1 Pehar = 3 hours. 1 Pehar = 64 (some says 60) gharis. 1 Ghari = 22.5 mins or 24 mins 1 Ghari = 60 Pal. 1 Pal = 22.5 seconds 1 Pal = 3 chasaas. 1 Chasaa = 7.5 seconds 1 Chasaa = 15 visaas. 1 Visaa = 0.5 seconds 1 Visaa = 15 Nimakh. 1 Nimakh = 0.033 seconds Hindus and Sikhs by convention take a day to begin at sunrise to sunrise. Muslims on the other hand consider period on a day to begin at sunset (after the magrib prayer) and end at next sunset. Christian day begins at midnight and end at the following midnight. Let me know your thoughts.
