Guruvar Vrat Vidhi 2026: How to Keep the Thursday Fast for Brihaspati, What to Eat, and the Katha
The Thursday fast honours Brihaspati and Vishnu. A 16-Thursday vow is the common form and can begin on any Thursday — the next is 10 September 2026. Yellow clothes, chana dal and jaggery, the banana-plant puja, the katha and udyapan, step by step.
The Thursday fast, or Guruvar vrat, honours Brihaspati (the deity of the planet Jupiter and the guru of the gods) and Lord Vishnu. A vow of 16 Thursdays is the most common form, and it can begin on any Thursday — the next one is 10 September 2026. The routine is simple: bathe in the morning, wear yellow, worship a banana plant with turmeric, offer chana dal (split Bengal gram) and jaggery, read the katha (the fast's story), and eat one plain sattvik meal. Steps, food rules, the story, the closing ceremony and every Thursday up to November 2026 follow.
Whose fast is Guruvar vrat, and why is it kept?
Brihaspati is regarded as the guru, or teacher, of the gods. In the jyotish (Vedic astrology) tradition, Guru — the planet Jupiter — is the karaka of knowledge, education, marriage, children and dharma. A karaka is simply the planet that a subject is linked with. Thursday is his day, which is why this fast is also called Brihaspati vrat.
Lord Vishnu is also regarded as the deity of Thursday. In many homes the main worship on this day is to Vishnu, with Brihaspati remembered alongside him. For a fuller picture of Jupiter and the beliefs around it, read our guide to Guru.
How many Thursdays, and when should I start?
A sankalp of 16 Thursdays is the common form. A sankalp is the vow you take before the first puja — silently or aloud — stating how many fasts you will keep and in what spirit. Some people vow fewer or more Thursdays, and some keep the fast for life.
You may start on any Thursday; the next one is 10 September 2026. In some homes the starting month is also fixed by tradition, so a quick word with the elders or your guru is the best first step.
How do I keep the Thursday fast, step by step?
- Bathe and wear yellow. Bathe in the morning and put on yellow or pale yellow clothes — yellow is regarded as the colour of both Brihaspati and Vishnu.
- Take the sankalp. On the first Thursday, hold water in your palm and state your vow — how many Thursdays, and with what intention. On later Thursdays, a brief remembrance is enough.
- Set up the puja space. Spread a yellow cloth on a clean spot. Place a picture or image of Lord Vishnu and Brihaspati Dev.
- Worship the banana plant. Pour water at the root of a banana plant. Offer turmeric (haldi), yellow flowers, chana dal and jaggery. Mark the stem with turmeric; you may tie a yellow thread around it. If there is no plant at home, worship one at a temple, or simply complete the Vishnu–Brihaspati puja at home — the vrat is not considered incomplete without the plant.
- Light the lamp and offer bhog. Light a lamp and offer chana dal and jaggery — these two are the principal offerings of this fast.
- Read the katha. Read or listen to the Guruvar vrat katha (a short version is below). Better still if the family sits together.
- Aarti and prayer. Perform aarti for Vishnu and Brihaspati Dev. Say what is in your heart in plain words — no fixed mantra count is required.
- Eat. In many homes one yellow, sattvik meal is taken, usually in the evening after the puja. Some people keep to fruit and milk.
Some households do not wash hair or do laundry on Thursdays. This is a custom, not a binding rule — if your family has never followed it, there is nothing to worry about.
What can I eat on the Thursday fast, and what should I skip?
| Item | Traditional practice |
|---|---|
| Chana dal and jaggery | The main offering; eaten as prasad after the puja |
| Yellow food | Plain food cooked with turmeric — dal, rice, roti |
| Fruit and milk | For those who keep a fruit-only (phalahar) fast |
| Meal timing | In many homes, one meal a day, usually in the evening after the puja |
| Banana | The plant is worshipped, so many families do not eat the fruit on this day; follow your home's custom |
| Skip | Onion, garlic, meat and alcohol — tamasik food |
A fast is not meant to be a hardship. Children, the elderly, pregnant women and anyone on medication can simply do the puja and eat normal sattvik food — that too counts as keeping the vrat.
What is the Guruvar vrat katha? (short version)
According to the katha, a king kept the Thursday fast every week and gave generously in charity. His queen disliked this — to her it all seemed pointless. At her urging, the king stopped both the charity and the fast.
Slowly the king's days grew hard, and he had to leave for a foreign land and labour for a living. There he saw an old woman keeping the Thursday fast and telling the katha. After hearing it, he took up the fast again. The story says that from then on his days gradually improved and he returned to his kingdom.
The moral is plain: do not abandon faith, giving and discipline midway — and if you slip, pick the thread up again.
Is the Sai Baba Thursday fast the same thing?
No. Devotees of Sai Baba of Shirdi also fast on Thursdays, but that is a separate, modern tradition with its own method, story and closing ceremony. If you belong to the Sai tradition, follow its vidhi; there is no need to blend the two. This article covers the Brihaspati–Vishnu vrat.
How do I do the udyapan?
Udyapan is the formal completion of a vow. On the Thursday your sankalp is fulfilled — the sixteenth, in a 16-Thursday vow — do the usual puja with a little more care:
- Bathe, wear yellow, worship the banana plant and Vishnu–Brihaspati as on every Thursday.
- Read the full katha and perform aarti.
- Offer chana dal, jaggery and yellow food; share the prasad with the family.
- As your means allow, gift yellow items — chana dal, jaggery, a yellow cloth — to someone with respect. It is about the gesture, not the quantity.
Continuing the fast after udyapan is your choice. If your family or guru has a different udyapan custom, follow that.
Which Thursdays fall between September and November 2026?
These dates are checked against our panchang engine. Any other observance on the same day is noted.
| No. | Thursday | Also on this day |
|---|---|---|
| 1 | 10 September 2026 | — |
| 2 | 17 September 2026 | Kanya Sankranti (the Sun enters Virgo) |
| 3 | 24 September 2026 | Guru Pradosh (the Pradosh fast falling on a Thursday) |
| 4 | 1 October 2026 | — |
| 5 | 8 October 2026 | — |
| 6 | 15 October 2026 | — |
| 7 | 22 October 2026 | — |
| 8 | 29 October 2026 | Karva Chauth |
| 9 | 5 November 2026 | Rama Ekadashi |
| 10 | 12 November 2026 | — |
| 11 | 19 November 2026 | — |
| 12 | 26 November 2026 | — |
If you take a 16-Thursday vow from 10 September, 12 Thursdays are complete by 26 November; the remaining four come after that. 29 October is also Karva Chauth — women who keep both usually let the Karva Chauth rules lead and keep the Thursday puja simple. 5 November is Rama Ekadashi — Ekadashi is regarded as Vishnu's day, so many people treat that Thursday as special. Sunrise, tithi and auspicious timings for each Thursday are in our daily panchang.
Frequently asked questions
What if I miss a Thursday?
There is nothing to worry about. If travel, health or menstruation makes you miss a Thursday, tradition allows you to carry the count forward — resume the next Thursday from where you stopped. Some homes add the missed Thursday at the end. Continue with faith; that is enough.
Can I keep the Monday and Thursday fasts together?
Yes, many people do. The deities and offerings differ, so do the two pujas separately. For the Monday fast's method and dates, see our Somvar vrat calendar.
Does the Thursday fast strengthen Jupiter in my horoscope?
In the jyotish tradition, Thursday is Jupiter's day and this fast is associated with Guru. Treat it as devotion and discipline — no fixed change in any planetary position can be guaranteed. Our article on Guru covers the planet and the common beliefs around it.
One last reminder — the method here is the general one. If your family's or your guru's way differs, follow theirs.
