Research question: What are the citations of seasons along with lunar Hindu months or lunar phases in Mahabharata?
This is extremely important tool for dating Mahabharata, using precession of equinoxes and seasons, which is a strong proof.
As of now, there are three well known such citations. Are there more such descriptions present?
1. Pandavas in Vana Vasa
16 teṣāṃ puṇyatamā rātriḥ parva saṃdhau sma śāradī tatraiva vasatām āsīt kārtikī janamejaya
And, O Janamejaya, the holiest night, that of the full moon in the month of Kartika in the season of autumn, was spent by them while dwelling there!
2. Krishna's mission of Peace.
7 kaumude māsi revatyāṃ śarad ante himāgame
sphītasasyamukhe kāle kalyaḥ sattvavatāṃ varaḥ
The month was (Kaumuda Kartika) under the constellation Revati. It was the season of dew, Autumn having departed.
3. Bhishma Nirvana
6 sa niryayau gajapurād yājakaiḥ parivāritaḥ dṛṣṭvā nivṛttam ādityaṃ pravṛttaṃ cottarāyaṇam
Accompanied by a number of priests he then set out of the city named after the elephant, having seen that the sun ceasing to go southwards had begun to proceed in his northward course.
28 māgho 'yaṃ samanuprāpto māsaḥ puṇyo yudhiṣṭhira
tribhāgaśeṣaḥ pakṣo 'yaṃ śuklo bhavitum arhati
O Yudhishthira, the lunar month of Magha has come. This is, again, the lighted fortnight and a fourth part of it ought by this (according to my calculations) be over.
