Who keeps the Wednesday (Budhavāra) vrat, and how is it done?

it is kept for Budha (Mercury) and Gaṇeśa, often for studies, speech and business, with green offerings and mung dal.

Wednesday belongs to Budha, the planet of intelligence, speech and trade, and in many homes also to Gaṇeśa. Students, people in business and those advised by an astrologer to strengthen Budha keep this vrat. It is commonly started on a Wednesday of the bright fortnight, for 7, 21 or 45 Wednesdays.

The pūjā is simple: offer dūrvā grass, green leaves or green moong, modak or laḍḍū to Gaṇeśa, and if you wish recite a Budha mantra or the Gaṇeśa Atharvaśīrṣa. One meal is taken, often of moong dal and green vegetables; some give green moong or green cloth in dāna.

This is one of the gentlest weekday vratas, easy to combine with school or office. If you only manage a short prayer and a lighter meal, that still honours the day.
