Solah Somwar Vrat 2026: Start Dates, Rules, Udyapan and Monday Calendar

Quick answer: Solah Somwar Vrat is a sixteen-Monday vow to Lord Shiva, often begun in an auspicious month such as Sravana and continuing well beyond it, with its own katha and a formal udyapan at completion. It is distinct from Sawan Somwar Vrat, which is kept only on the Mondays of Sravana.

Solah Somwar Vrat is a traditional sixteen-Monday vow to Lord Shiva. It is often begun in an auspicious month — frequently Sravana — and continues across sixteen consecutive Mondays, ending with a formal udyapan. It is a distinct observance from Sawan Somwar Vrat.

Solah Somwar Vrat is not the same as Sawan Somwar Vrat

Sawan Somwar Vrat is kept on the Mondays of the month of Sravana only. Solah Somwar Vrat is a sixteen-week vow that begins on a chosen Monday and runs for sixteen Mondays — usually well past the month of Sravana — with its own katha and a concluding udyapan. Conflating the two is the most common error around these observances.

Health note: fasting is a personal choice. People who are pregnant or breastfeeding, who have diabetes or blood-pressure conditions, who take regular medication, who are elderly or unwell, or who have any history of disordered eating should consult a doctor before fasting. Tradition itself provides for observing without fasting. This is descriptive of tradition, not medical advice.

Because Solah Somwar is a sixteen-week commitment, the health considerations above matter especially — observe in a form that is safe and sustainable for you, and remember that tradition provides for observance without fasting.

Starting the vrat in Sravana 2026

Many devotees begin the Solah Somwar Vrat on an auspicious Monday, and the Mondays of Sravana are considered especially suitable. If you begin on a Sravana Monday in 2026 (for example 17 or 24 August), count sixteen consecutive Mondays to your completion date, and mark the udyapan for the sixteenth. Confirm your start date with your purohit.

The rules, as tradition holds them

• Observe each Monday with a bath, sankalp, Shiva abhishekam and puja, and the vrat katha.
• Keep the vrat in a form suited to your health — the tradition does not rank one form above another.
• Maintain the observance across all sixteen Mondays where possible.
• Conclude with the udyapan on the sixteenth Monday.

If a Monday is missed

Tradition provides accommodations — many devotees make up the observance or continue with sincerity rather than abandoning the vow. Do not approach this with fear; devotion and honest effort are what the tradition values.

Udyapan

The udyapan is the concluding ceremony performed on completion of the sixteen Mondays, typically with a fuller puja, the katha, feeding of brahmins or the needy, and offerings, as your family and purohit guide. It formally completes the vow.
