😅NVM, the basic framework is this. Day 1- Nahae khae, we eat after bathing, and then normal day. Day 2- Kharna, fast is done on this day, without water, and prasada of jaggery, chapati, with fruits is taken at night and Paṇḍita do the kathā of chaṭha pūjā. From there the nirjala vrata for evening argah begins. Day-3, evening argah, thekua, etc is made on this day, and in evening we fill the koshi with fruits, etc and take it to ghāṭa, and do the pūjā of Chatti maa and Sūrya argah at evening, after Paṇḍita recites some chaṭha kathā. After giving aragha, we return to home. Day 4. Morning argah, here we go to ghata around 2 hours before sunrise, take sugarcane with us, and also the koshi with fruits and this time Puri, channa, is also added as prasāda, with dipak on top. And after sometime we take sugarcane back to home, and then wait for sunrise, Paṇḍita do the chaṭha kathā in morning and then argha, and then we return after taking prasāda. And then the pūjā is concluded. This was a basic overview, there are regional variations as well, like in some region people will dip while giving argah, we only stand in water and touch the shup [a container made of bamboo, with prasāda], similar in our side, we do a thing which is calle "koshi bharna [see pic]" after returning from ghāṭa in evening [not all regions done this] and sing song of Chaṭhī Mā, taking the sugarcane back is also not followed in all regions, some regions take sugarcane to ghāṭa on both days evening and morning,we only take that in morning. In pic, the whole thing is taken to ghāṭha in bamboo basket [daurā], both days, we prepare this in evening [after returning from ghāṭa on argah day 1], Puri, Diya is taken to ghāṭha on morning day. For argah seperate basket, or baskets of bamboo [shuppi] or metal [if someone has taken some vow] is used. Idk about other regions, but we trace the pūjā from Mahābhārata kāla, performed by Draupadī, after listening to the Sukanyā and Ṛṣi Cyavana. In our kathā, Sukanyā treated Ṛṣi by the blessings of Chaṭha pūjā.
