One major criticism of the series: I felt it would have been much easier to understand the whole thing if you had started off with the third section: Ahoratra, etc. instead of starting off directly with Chandramana. This is majorly because for someone who has no background of this field of astronomy (like me), the very concept of the ecliptic is extremely confusing. Even after you showed the Stellarium animations in the beginning, I still did not understand why it was that the Sun was moving on the ecliptic so slowly. In fact, the very concept of the ecliptic itself wasn't clearly explained, relegating it to the Stellarium animations to hopefully convey the idea. Imagine the plight of a confused school student (if at all you intend to take it to the schools), who would wonder as he/she watches the Stellarium animations, as to why it is that the Sun (or for that matter, any of the planets) doesn't move through all the 12 rashis in the course of a single day, because anyway the Sun is moving relative to the earth, so it would be at different points in the sky. I had exactly this same confusion throughout until the very third section of the whole series. It was only after you explained the Ahoratra stuff with those explanations about the relative motion of the Sun against the background of the Nakshatras did I finally understand that it was this relative motion with respect to the stars that was causing the movement along the ecliptic (perhaps this was when I finally understood the idea of the ecliptic, I think). When someone sees the calculation that the Sun reaches the same point after 23:56 hours and not 24 hours, then they will realize that there is a movement happening after 24 hours, which means that the Sun is not really at the same point in the sky after 24 hours, but has moved further, and this will then make them realize that this movement is against the backdrop of the stars. So if you are taking this to the schools, it would be better to start with this section before moving on to Chandramana and Sauramana. Granted, starting this way might not bedazzle the audience with the dance of the Stellarium animations, but it is better to have your audience convinced rather than confused, even if at the cost of putting fancy animations to a later point.
Thank you for the detailed critique. The ecliptic is explained in Episode 1 but it is indeed possible more explanation is needed, particularly when it comes to students.
Namaste mahodaya, all your episodes were very informative and interesting. Every one should know this jyotishya vijnana of Bharat. I really appreciate your efforts. Thank you so much.
Sir, Thank you very much for the great work you have done in explaining Hindu calendar and calendric elements. It was a pleasure watching the series and a bit saddening to hear that the series has ended. I hope you will come up with some new topics to enlighten us. All the best to you for your project to take this to the schools.
You are good at this and you are making people realise the importance of ancient Indian supremacy in their precision and accuracy...I understood all your videos watching it for the first time only without any reputations... But suggest me a book regarding the ancient Indian temple architecture also ....easily understandable books...I followed the Google for the best books but they are not easily understandable...so suggest me few books on South Indian temple architecture
All good things have to end. But good things rnd in a jiffy. A very interesting series which gives excellent knowledge about Hindu system of measuring time for laymen and uninitiateds like me. Your tremendous efforts are commendable. One small trivial question - in the Drik Panchanga, on the line between sunrise and sunset, there is a symbol of a tree. Does it represent any astronomical event?
Sir, The early Vedic period divided the day into 30 Muhurtas, 15 by day and 15 by night.Each Muhurta had 15 Sub Muhurtas. Why such a type of division? Is it because they used a sidereal day instead of Solar/savan day. It appears Sexagesimal system? Further divisions of the day were introduced at a later period ( Ghatika, Nadi etc)Your animation also suggests that Hindu day was sidereal and not Solar/Savan day, hence the discontinuity in the Hindu clock vis a vis compared to the modern/ Solar clock. Please clarify.
Thank you for your comments. I do not know any source for the early vedic period definition of ahoratra. If you know a source, pls post that here. I will be interested in studying it. drikpanchang.com uses such a definition of equal day and night of 15 muhurta each (what you call sub-muhurtha is nothing but nadi) and they say it applies to savana ahoratra and hence muhurtha (and hence nadi) is of variable length! I do not find this satisfactory. It is necessary to study the early vedic source(s) carefully. Surya Siddhanta defines two Hindu days - nakshatra (what you call sidereal) ahoratra and savana ahoratra. It defines nadi, vinadi and prana as subdivisions of nakshatra ahoratra. Then it says that "udaya to udaya is savana; savana is used to regulate the time of yajña" (chapter XIV verse 18). My videos are based on this reading of the Surya Siddhanta. The modern solar clock is a completely different ballgame. It hinges on 24 hours which is the mean solar day. I do not find any reference to such a construct in the Surya Siddhanta chapter pertaining to calendrics. Yet, all explanations of nadi on the Internet blithely assume "An ahoratra is 24 hours" and proceed. I am arguing this assumption is invalid.
@@dilipranade Oh. For this I have no answer. If you look at it as nadi instead of muhrtha then it indeed becomes sexagesimal. Ancient Babylonians too used a sexagesimal number system. Why? I have no clue.

Namaskaara Kishoreji,
Was actually expecting and waiting for your video today. Thanks for that. Good One.
Will wait for more videos
:-) Thank you for the kind words!
Very much insightful, clean, clear explanation with animation. And what a nice divinity commentary to end the series!. Thank you.
Namaste mahodaya, all your episodes were very informative and interesting. Every one should know this jyotishya vijnana of Bharat. I really appreciate your efforts. Thank you so much.
Thank You!
Thank you, Kishore! This was a very interesting and informative series. Appreciate all the effort that has gone in, in putting this together!!
Thank you Sampath!

Thank you! I had completely overlooked that tree. I don't know what that represents. If I figure that our I will let you know here.
I think the tree just adorns the horizon. There are also a few "birds" above the horizon. The shape of the tree changes randomly too! :-))
Also, the series only barely scratched the surface, leaving much more to be desired.
great 🙏

@@Ahargana Taittriya Brahaman verses 3.10.9 and 3.10.1 give out the names of 15 Muhutras
The main point is why 30 parts or rather how did they arrive this figure of 30?
