On comparing the predictions of temperature using both Hindu and Gregorian Calendars, it is observed that in the Hindu Calendar approach, the temperature variation has shown an identifiable pattern. The prediction model performed well and followed the actual trend in a better way.
Also, as the pattern is more clear and predcitable in this case, we can get more insights and better results from the models built on Lunisolar calendar approach like the Hindu Calendar. Considering the Gregorain Calendar approach, it shows rapid change in the temperature over the time and could not follow a predictable pattern.
