Tuesday, which is known as Mangalwar or Chowai or Chovazhcha, is considered inauspicious by some Hindu communities, especially in South India (Kerala). No journey is commenced on Tuesday as it is bad. Auspicious ceremonies are also avoided on the day. Some scholars indicate that that it is suggested in the Brihat Samhita of Varahamihira that Tuesday should be avoided for auspicious functions.
Mangalwar or Tuesday is ruled by Mars or Mangal. Mars is also known by the name of Angarak, Kujan, Agneya and this all indicates that the planet is red and is associated with heat. He is also believed to kick start fights and is also considered to be responsible for cuts and bruises on the body. He is also believed to create unwanted competitions among people.
(Probably this is the reason for Hair cutting Saloons in Tamil Nadu are closed on Tuesdays!!)
Tuesday begins at the highest influence point of Mars and therefore he is believed to have control throughout the day.
In
Jyotish astrology,
Mangala (
Devanagari: Ma
ṅgala) is the name for
Mars, the red planet. Mars is also called
Angaraka ('one who is red in colour' also called Rakta varna whose color is like blood ;He is the god of war and is

In
Vedic astrology Mangala is considered a malefic of the first order; Mangala represents drive and physical energy, self-confidence and ego, strength, anger, impulsiveness, heroism and adventurous nature. Mangala rules over blood, muscles and bone marrow. He is associated with battle, war and soldiers.
Ancient Babylonians first created the week, dividing it into seven days. Each day was named for one of the seven known moving bodies in the sky: the sun, the moon, Mars, Mercury, Venus, Jupiter and Saturn. The Babylonians believed that each of these heavenly objects influenced people's lives on the days named for them. "Mars Day" was Tuesday. Because of the planet's red color, the Babylonians associated Mars with Aggression and performed special ceremonies on Tuesdays to avoid the fearsome influence of this warlike planet.
"Tews" was the English name for the god of war.
Hindus wear red-colored clothes on Tuesdays and offer red flowers to Lord Hanuman. 'Moonga' is the preferred gem of the day.
These are some of the reasons why Tuesday is held inauspicious.
But Tuesday is considered the most auspicious day to worship Lord Hanuman – Sankat Mochan. Tuesday is also highly auspicious to worship Lord Ganesha.
That’s why I do not hesitate to travel on Tuesdays and Travel Tickets to India is cheaper on that day as compared to other days!!
