In Hindu tradition, Tuesday, known as "Mangalvar," is dedicated to Lord Hanuman. This day holds significant spiritual and astrological importance for several reasons.

Firstly, Tuesday is linked to the planet Mars (Mangal), which represents strength, courage, and vitality. Lord Hanuman embodies these qualities, making this day ideal for seeking his blessings. Worshiping Hanuman on Tuesdays is believed to help devotees overcome challenges and gain confidence.

Secondly, a key event in the Ramayana occurred on a Tuesday when Hanuman found Goddess Sita in Lanka. This act of bravery and devotion further cements the connection between Hanuman and this day.

Additionally, Hanuman is said to have been born on a Tuesday during the Chaitra month, adding to the day's significance. Both Mars and Hanuman are associated with the fire element, which enhances their spiritual link.

Devotees often observe rituals such as fasting, visiting temples, and reciting the Hanuman Chalisa on Tuesdays. These practices are aimed at seeking Hanuman's protection, strength, and prosperity in their lives. 

Thus, Tuesday has become a special day for honouring Lord Hanuman in Hindu culture.
