Panch Baan (Five Arrows / Pancha Bana) is a muhurtha consideration showing inauspicious time windows (Baan yogas) based on the combination of the day of week (vara), tithi, and nakshatra. Travel, new ventures, vehicle purchases, and important ceremonies are traditionally avoided during Baan yoga periods. The Panch Baan calendar lists all such periods throughout the year for reference when planning auspicious activities.
