We know that there are 7 days in a week and they are sunday, monday...etc. In tamil calender its nyayiru, thingal, sevvai.. etc. We know that sunday - nyayiru - xxxxx in arab calender-all these denote the day related to sun.. Next is monday and monday-thingal-YYYY -all these denote moon... next is tuesday- sevaaai ...goes on.Like this, we have 7 days denoting 7 planets.
I was wondering and thinking about this:
1. Why is sunday (that day) considered for sun and monday (considered) for moon etc.. and how it is common in all calenders, tamil, english, arab? I mean to ask why/how in all calenders its followed in the same order sunday, monday?
2. We adjust days in leap years, we adjust days in months.. we never adjust days in a week in any calender anytime. Its fixed unlike days in a month/ year-why?? That too, they are the fixed variables in all calenders (english, tamil, arab etc.) how??
3 In a week, we(our ancestors) have considered 7 planets for 7 days - except earth, neptune and pluto.We (I) can assume that everything is around earth and so, we shall leave earth.. but why we should we leave neptune and pluto...any idea??? why not 9 days a week?? Heard from some people that those planets were discovered later. Some have told me that they were shed out from other main planets..
I have some wild guesses and have asked few friends. Not heard a convincing answer yet. Any piece of info or guess??
