Karthika Somavaram — the Mondays of Karthika Masam — are among the most meritorious days of the year to worship Lord Shiva. In 2026 they fall on 16, 23, 30 November and 7 December. They are the heart of Karthika Masam 2026.

Karthika Somavaram 2026 Dates

  • Mondays (IST): 16 November, 23 November, 30 November, 7 December 2026
  • Deity: Lord Shiva — Rudrabhishekam, bilva, Deepam
  • Abroad: Mondays are the same Gregorian days worldwide

Significance

Karthika is hailed as the most meritorious month, and Monday is Shiva’s day — so Karthika Somavaram doubles the merit of Shiva worship. Devotees combine the pre-dawn Karthika Snanam, Shiva abhishekam, fasting and the signature Deepa Daanam (lamp offering). Many also keep the Kedareswara Vratam in this season.

Vrat & Puja Vidhi

  1. Take the Karthika Snanam (pre-dawn holy bath) and a sankalpam.
  2. Perform abhishekam on the Shivalinga with water, milk and bilva (bel) leaves.
  3. Keep a Monday fast and light lamps — the Akasha Deepam (sky-lamp) and, where kept, a 365-wick deepam.
  4. Chant Om Namah Shivaya and the Mahamrityunjaya mantra; recite the Rudram where possible.
