It is funny how the world believes that 7 day week is a western concept!
It is absurd how the whole world believes that the 7 day week is a western approach! 7 day week is not a concept borrowed from Romans as it is generally believed.
The 7 day week is not really based on western calendar. Firstly, let’s look at how classic predictions ( Jyothisha Shastra ) of the Vedas for answers to these questions:
Why do we have only 7 days in a week? Why can’t we have 8 or 9? What is an hour? Why do we have only 24 hours in a day? Why can’t we have 30 or 40 units and call it an hour?
Ancient Indians were so well versed that they often used 4 to 5 different units of time. If you ask your Indian grand mother, she might have told you that during her days, people measured time in a weird unit called ghati/ghadiya (1 ghati = 24 minutes).
1 day is the time lapsed between two sunrises. Sandhi in sanskrit means knot or junction and hence the junction points are named as pratah sandhya(Early morning) and sayam sandhya (Evening) which divide the standard day into two halves i.e from sunrise to sunset and sunset to the next sunrise.
Since there are 12 zodiac constellations, each constellation is assigned a part of the half a day unit and hence 12 parts in half a day each, together 12+12 = 24 units. This is the concept of hora or HOUR. (Yes, hora is the standard hour. English unit of time and Sanskrit unit of time named similarly. Strange coincidence, don’t you think so?)
Just as there are constellations associated with each hora, each graha is assigned rulership of individual hora. The structure of the terrestrial rulership of hora’s is as follows.
1) Surya (Sun/SUN-DAY) followed by
2) Shukra (Venus/FRI-DAY) followed by
3) Budha (Mercury/WEDNES-DAY) followed by
4) Soma (Moon/MON-DAY) followed by
5) Shani (Saturn/SATUR-DAY) followed by
6) Guru (Jupiter/THURS-DAY) followed by
7) Mangala (Mars/TUES-DAY).
In Indian Prediction science (jyothish shastra), the rising sign at the time of sunrise is noted down and is considered very important to make any astronomical/astrological calculations regarding a chart, esp. to find out the janma lagna (Birth time), it is is very essential. So, the rising sign is very important. Likewise, the terrestrial rulership of the hora during the time of sunrise is noted down. The planet that rules the hora at the time of sunrise is assigned the rulership of the whole day.
And hence, The day Ravi-vara (or Sun-day) is named after Ravi/Sun who is assigned lordship of the day because he rules the hora at the time of sunrise of that day. Now, following Sun, the next hour after sunrise is ruled by Shukra followed by the rest. In the above mentioned structure of rulership of hora’s, calculate the next ruling planet that comes after 24 horas, i.e
1st hour by Ravi,
2nd hour by Shukra…. Read more
