It appears that you just got flowed into emotional rivers of "Full moon in phalguni" of the previous researchers. You hardly could connect with the word Vishuva ( tropical equinox- in vasanta, yet another evidence from the same brahmana to be the first month of the year) which I have explained in detail with the etymological references. Please do not show your weakness of not reading the text.

Further, we can discuss only if you provide

1. With the evidence where the "Full moon" is mentioned in Taittiriya brahmana, which you won't be able to.

2. Be specific, first decipher the Tai. Br reference.

3. You compared with Gopatha by saying that all the brahmanas were written at the same time( your quote on twitter), that is completely untrue and I don't know how you came to this conclusion. Kindly elaborate on that. Gopatha also has evidence of vasanta as the first month, how will you conclude that ( surprised? ).

4. I completely rebut your rejoinder on the basis of absence of "Full moon" evidenc in the Taittiriya Brahmana.
