Sawan Somwar 2026: Dates, Vrat Vidhi, and What You Should Never Offer Shiva

Through Sawan, something shifts in the sound of a Shiva temple. The bell is the same, but under it runs a constant thin trickle — water, then milk, then water again — poured over the Shivling from morning until night. Outside, the monsoon is doing the same thing to the whole country. And on the roads, lines of kanwariyas walk barefoot with pots of Ganga water balanced on their shoulders, heading for a temple that might be a hundred miles off. This is the month Shiva is closest, and Monday — his own day — is when devotees come nearest of all.

In 2026, Sawan runs from 30 July to 28 August in North India, and it carries four Mondays. Here they are, with everything you'll want for the vrat.

Sawan (North India): 30 July – 28 August 2026

Sawan Somwar: 3, 10, 17 & 24 August 2026 (four Mondays)

Deity: Lord Shiva

Fast: sunrise to evening; broken after the Shiva puja

The four Mondays - and why your dates might differ

The date you keep depends on which calendar your region follows, and this is where a lot of confusion starts.

• North India (Purnimanta calendar): 3, 10, 17 and 24 August.

• Maharashtra, Gujarat & South India (Amanta calendar): Sawan runs 13 August – 11 September, so the Mondays are 17, 24, 31 August and 7 September.

If your family's dates don't match a neighbour's, this is usually why — the two calendars begin Shravana a fortnight apart. Follow the one your household has always kept; both are correct.

Why Monday, and why Sawan

The reason sits inside one of the oldest stories we have. When the devas and asuras churned the ocean, the first thing to surface wasn't nectar — it was halahal, a poison strong enough to end creation. Shiva drank it to save everyone, and Parvati pressed his throat so it couldn't go further; it lodged there and turned his throat blue. That is why he is Neelkanth, the blue-throated one. To cool the burning, the gods poured water over him without stopping. Every pot of water a devotee tips onto the Shivling in Sawan is a small repeat of that moment. And Monday belongs to the Moon, which rides on Shiva's head — so of all the days, this one is his.

Sawan Somwar vrat vidhi, step by step

1. Bathe early and take a sankalp (resolve) to keep the fast.

2. Do Jalabhishek — bathe the Shivling with water, then raw milk, then water again.

3. Offer bel patra (three leaves joined, smooth side down), white flowers, chandan, dhatura, akshat, and bhang if it's your custom.

4. Light a diya and dhoop, and chant Om Namah Shivaya.

5. Read or listen to the Sawan Somwar katha.

6. Break the fast in the evening after the Shiva puja, ideally during Pradosh Kaal.

You don't need a temple for any of this. A small Shivling at home — or even a supari stood in for one — is enough. The pouring and the intent are what carry the puja.

The fast — keep it steady, not severe

There's more than one way to keep Sawan Somwar, and no single "correct" level:

• Nirjala: without water — the strictest, and not meant for everyone.

• Phalahar: fruit, milk, and vrat foods like sabudana, samak rice, singhara flour, with rock salt (sendha namak).

• One meal: a single sattvic meal after the evening puja.

Pick what your body can sustain across four Mondays. A vrat is meant to be tapas, not a health risk — if you're unwell, pregnant, or on medication, the fruit-and-milk route is the sensible one. Grain, regular salt, onion and garlic are usually set aside for the day.

The offerings Shiva won't take

This is where a lot of well-meaning people slip. On the Shivling, avoid:

• Tulsi — offered to Vishnu, not Shiva; there's an old story behind the exclusion.

• Haldi — tied to the feminine and to Vishnu, and kept off the Shivling.

• Ketaki (kewda) flower — cursed in the Shiva Purana, and never offered.

• Sindoor, and coconut water for abhishek — traditionally avoided.

What Shiva does welcome is plain: water, raw milk, bel patra, white flowers, bhang, dhatura and ash. He's the easiest deity to please — the tradition doesn't call him Bholenath for nothing.

The mantras

The five-syllable name is enough on its own: Om Namah Shivaya. On the Mondays, many also recite the Mahamrityunjaya mantra — the great verse for health and protection:

ॐ त्र्यम्बकं यजामहे सुगन्धिं पुष्टिवर्धनम्।
उर्वारुकमिव बन्धनान् मृत्योर्मुक्षीय मामृतात्॥

The other Sawan vrats worth knowing

Sawan Somwar doesn't stand alone — the month is full of observances that often run together:

• Solah Somwar: sixteen consecutive Mondays, begun in Sawan, kept especially by unmarried girls praying for a good husband.

• Mangala Gauri Vrat: the Tuesdays of Sawan, kept by married women for their husband's long life.

• Pradosh Vrat: the trayodashi (13th) of each paksha, worshipped at twilight.

• Masik Shivratri, and Nag Panchami on 17 August — which is the same Monday as the third Sawan Somwar this year.

Frequently asked

How many Sawan Somwar are there in 2026?

Four in North India — 3, 10, 17 and 24 August. The Amanta regions also have four, but on different dates (17, 24, 31 August and 7 September).

Can I drink water during the Sawan Somwar vrat?

Yes, unless you've chosen a nirjala (waterless) fast. Most people keep a phalahar fast with water, fruit and milk.

What should I not offer on the Shivling?

Tulsi, haldi, ketaki flower, sindoor and coconut water are traditionally avoided.

Can I do the puja at home without a temple?

Yes. A small Shivling at home, Jalabhishek with water and milk, bel patra and Om Namah Shivaya makes a complete puja.

When do I break the fast?

In the evening, after the Shiva puja — many break it during Pradosh Kaal, around dusk.
