As Chandra rules Monday and is auspicious by its nature, thus Monday is considered to be a good day and all auspicious works can be done during it. The nature of it is movable (in ancient Sanskrit - "Chara" or "Chal"), thus all "movable" works are good at this weekday. In combination with "movable" Nakshatras (Punarvasu, Swati, Shravana, Shatabhisha and Dhanishta) activity related to this Nakshatras will be very fruitful. As for effectiveness - Monday is effective during night-time. This day is auspicious for everything related to white color, "manasic" works, working with consciousness and positive thinking (as Chandra is a ruler of this day, Manas and consciousness). All works that somehow are related to mother's aspect (worshipping of Ma, helping mother, etc) are very auspicious at this day (as Parvati is a tutelary Devata of it). As Adhi-Devata of Monday is Apas (or Jala) normalizing and regulating of emotional state and feelings should be done during this day.
