The fourth day of the dark half of every month is the day for the observance of the chaturthi-vrat (or choth-vrat). This vrat is observed in honour of the god Ganpati and by men only. The devotees fast on this day, bathe at night after seeing the moon, light a ghi lamp, and offer prayers to the moon. They also recite a pāth containing verses in honour of Ganpati, and, after worshipping that god, take their food consisting of some specially prepared dish. This vrat is said to fulfil the dreams of the devotees.[203]

The day for the chaturthi-vrat in the month of Bhādrapad (the 11th month of the Gujarati Hindus) is the fourth day of the bright half instead of the fourth day of the dark half,[204] and on this day (Ganesh Chaturthi[205]) the moon is not worshipped. The very sight of her is regarded as ominous, and is purposely avoided.[206] The story is that once upon a time the gods went out for a ride in their respective conveyances. It so happened that the god Ganpati fell off his usual charger, the rat, and this awkward mishap drew a smile from Chandra (the moon). Ganpati, not relishing the joke, became angry and cursed Chandra saying that no mortal would care to see his face on that day (which happened to be the fourth day of the bright half of Bhādrapad). If any one happens to see the moon even unwittingly on this day, he may expect trouble very soon.[207] There is one way, however, out of the difficulty, and that is to throw stones on the houses of neighbours. When the neighbours utter abuse in return, the abuse atones for the sin of having looked at the moon on the forbidden night. The day is therefore called (in Gujarat) Dagad-choth, i.e., the Choth of stones.[208]

On the fourth day of the dark half of Phālgun (the 5th month of Gujarati Hindus) some villagers fast for the whole of the day and remain standing from sunset till the moon rises. They break their fast after seeing the moon. The day is, therefore, called ubhi (i.e., standing) choth.[209]

Virgins sometimes observe a vow on Poshi-Punema or the full-moon day of Pausha (the 3rd month of the Gujarati Hindus). On this day a virgin prepares her evening meal with her own hands on the upper terrace of her house. She then bores a hole through the centre of a loaf, and observes the moon through it, repeating while doing so a verse[210] which means: O Poshi-Punemadi, khichadi (rice and pulse mixed together) is cooked on the terrace, and the sister of the brother takes her meal.[211] The meal usually consists either of rice and milk or of rice cooked in milk and sweetened with sugar, or of kansār. She has to ask the permission of her brother or brothers before she may take her food; and if the brother refuses his permission, she has to fast for the whole of the day.[212] The whole ceremony is believed to prolong the lives of her brothers and her future husband. The moon is also worshipped at the time of griha-shānti, i.e., the ceremonies performed before inhabiting a newly-built house.[213]

If the moon is unfavourable to a man born under a particular constellation, on account of his occupying either the 6th, the 8th or the 12th square in a kundali[214] (see below) prayers are offered to the moon; and if the occasion is a marriage, a bell-metal dish, full of rice, is presented to Brahmans.[215]

The appearance of the moon and the position of the horns of her crescent at particular times are carefully watched as omens of future events. Cultivators believe that if the moon is visible on the second day of the bright half of Āshādh (the 9th month of Gujarati Hindus), the sesamum crops of that season will be abundant; but if the moon be hidden from sight on that day, the weather will be cloudy during the whole of Āshādh, and will prove unfavourable to vegetable growth.[216] If the moon appears reddish on a Bīj day (or the second day of the bright half of a month), and if the northern horn of the crescent be high up, prices in the market are believed to rise; if, on the other hand, it is low, it prognosticates a fall in prices. If the two horns are on a level, current prices will continue.[216]

Similarly, the northern horn of the crescent, if it is high up on the Bīj day of Āshādh, augurs abundant rainfall; if it is low, it foreshadows a season of drought.[217]

If the moon presents a greenish aspect on the full-moon day of Āshādh, excessive rains may be expected in a few days; if on that day she rises quite clear and reddish, there is very little hope of good rains; if she is partly covered by clouds when she rises and then gets clear of the clouds, and then again disappears in the clouds in three ghadis,[218] three pohors,[218] or three days, rain is sure to fall.[219]
