A tale of two Varshas: What is the difference between nirayana saura varsha and sayana saura varsha?

We have seen a solar new year start with Mesha sankranti. That is only one of two types of solar years in the Hindu calendar. Since meshadi and rashis are niryana elements, the solar year begining with Mesha sankranti is a nirayana sayura varsha (sidereal solar year). We have also seen that uttarayana and dakshinayana are two halfs of a saura varsha. This implies that there is another possible saura varsha that starts when uttarayana begins and ends when the subsequent dakshinayana ends (i.e. from one winter solstice to the next winter solstice). Since uttarayana and dakshinayana are sayana elements, a saura varsha defined this way would be a sayana saura varsha (tropical solar year). Since the winter solstice is continually precessing in a retrograde direction, the duration of a sayana saura varsha is 20 minutes 24 seconds shorter than that of a nirayana saura varsha.
