Why Each Weekday Has Its Own Deity
In Vedic tradition the seven days of the week are named after the seven visible grahas - Sun, Moon, Mars, Mercury, Jupiter, Venus and Saturn - and each graha is governed by a deity. Worshipping the ruling deity on their day aligns your prayer with the day's cosmic energy, which is why tradition says the same prayer gives a bigger result when offered on the right day.
This is also why weekday vrats exist: Somvar vrat for Shiva, Mangalvar for Hanuman, Budhvar for Ganesha, Guruvar for Vishnu and Brihaspati, Shukravar for Lakshmi, Shanivar for Shani and Hanuman, and Ravivar for Surya. You do not need to observe every vrat - but knowing the day's deity lets you direct even a two-minute prayer correctly.
The Seven Days and Their Deities
- Monday (Somvar) - Lord Shiva. Offer water or milk on the Shivling, wear white, chant Om Namah Shivaya. The Somvar vrat is kept for health, marriage and peace of mind.
- Tuesday (Mangalvar) - Hanuman ji (and Mangal dev). Offer boondi or laddu, wear red, recite the Hanuman Chalisa. This vrat gives courage and removes fear and debt.
- Wednesday (Budhvar) - Lord Ganesha (and Budh dev). Offer green moong or durva grass, wear green, chant Om Gan Ganapataye Namah. Worshipped for wisdom, studies and new beginnings.
- Thursday (Guruvar) - Lord Vishnu and Brihaspati (Jupiter). Offer yellow items - chana dal, turmeric, banana; wear yellow; chant Om Namo Narayanaya. The Guruvar vrat brings knowledge, prosperity and a good guru.
- Friday (Shukravar) - Goddess Lakshmi and Santoshi Mata. Offer white sweets and lotus flowers, wear white or cream, chant Om Mahalakshmyai Namah. The day for wealth and household harmony.
- Saturday (Shanivar) - Shani dev and Hanuman ji. Offer mustard oil, black sesame and urad; wear dark blue or black; chant the Shani mantra Om Sham Shanicharaya Namah or the Hanuman Chalisa. Softens Sade Sati and removes obstacles.
- Sunday (Ravivar) - Surya dev. Offer arghya (water) to the rising sun, wear red or orange, chant Om Suryaya Namah or the Aditya Hridaya Stotra. For health, vitality and fame.
How to Use This Guide Daily
You do not need a full puja every day. A simple daily rhythm is enough:
1. Morning: after bath, remember the deity of the day and chant their mantra 11 or 21 times. 2. Colour: wear or keep something in the day's colour - even a handkerchief or thread. 3. Food: if you keep the day's vrat, eat only falahar or the day's permitted food; otherwise simply avoid tamasic food that day. 4. Evening: light a diya and offer a short aarti or stotra of the day's deity.
If your need is specific - marriage, exams, debt, health - give special attention to the day whose deity governs that area, and keep that one vrat sincerely for at least 7 or 16 weeks.
What People Ask Most
Which god should I worship on Wednesday?+
Wednesday (Budhvar) is dedicated to Lord Ganesha and the planet Mercury (Budh). Offer durva grass and green moong, wear green, and chant Om Gan Ganapataye Namah. It is considered the best day for prayers related to studies, intellect, business and new beginnings.
Can I worship other gods on any day?+
Yes. The weekday-deity system adds power to your prayer but never restricts it - you may worship any deity on any day. Your ishta devta (chosen deity) is always appropriate. The weekday rule is a helpful addition, not a rule that forbids.
Which day is best for starting a new work?+
Wednesday (Ganesha - remover of obstacles) and Thursday (Vishnu/Brihaspati - wisdom and growth) are traditionally preferred for new ventures, while Monday suits spiritual beginnings and Friday new purchases for the home. For important starts, also check a shubh muhurat.
