Masik Karthigai in June 2026 falls on Friday, 12 June 2026, when the Krittika nakshatra prevails in Jyeshtha month. It is the monthly day of lamps — sacred to Lord Murugan, who was nursed by the six Krittika mothers, and to Shiva. Across Tamil homes and the Tamil diaspora, rows of oil lamps glow at dusk. This short HinduTone guide covers the date, the ritual and the meaning. Find it in the June 2026 Hindu festivals calendar.

Significance

Karthigai is intimately tied to Murugan — also called Kartikeya, “son of the Krittikas.” When the divine child was placed in the Saravana reeds, the six Krittika star-mothers nursed him, and he merged his six forms into the six-faced Shanmukha. The Krittika nakshatra is therefore his star, and its monthly return is his day. Karthigai is also a Shiva festival — the great Karthigai Deepam recalls the infinite column of light (the jyotirlinga) by which Shiva revealed his limitless nature. Lighting lamps is thus an act of welcoming the divine light into the home.

The Deepam Ritual (Step by Step)

  1. Clean the house and the entrance; draw a kolam if you keep the custom.
  2. At dusk (pradosha time), light rows of traditional oil lamps — at the altar, doorway and windows.
  3. Offer simple naivedyam: pori (puffed rice), aval (flattened rice), jaggery, banana.
  4. Chant Om Saravanabhavaya Namah (Murugan) and Om Namah Shivaya (Shiva).
  5. Sit a few minutes before the lamps in quiet gratitude; share prasadam.

Mantras

ॐ शरवणभवाय नमः — Oṃ Śaravaṇabhavāya Namaḥ (Murugan), and ॐ नमः शिवाय — Oṃ Namaḥ Śivāya (Shiva). Either or both are traditionally chanted while lighting the lamps.

How the Tamil Diaspora Can Observe Masik Karthigai

  • Light a row of oil lamps (or LED/ghee diyas where open flames are restricted in apartments) at dusk — the heart of the observance.
  • Visit a local Murugan or Shiva temple in the evening if one is near.
  • Make a simple pori/aval naivedyam; involve children in arranging the lamps.
  • Source cotton wicks and lamp oil from Indian grocers; tealight ghee diyas are a safe apartment alternative.

Frequently Asked Questions

Is Masik Karthigai the same as Karthigai Deepam?

No — the grand Thiru Karthigai / Karthigai Deepam is in the Tamil month of Karthigai (Nov–Dec). Masik Karthigai is its monthly echo on each Krittika-nakshatra day.

Can I light LED lamps instead of oil lamps?

Traditional oil or ghee lamps are preferred, but where open flames are not allowed (many apartments abroad), ghee tealights or LED diyas are an accepted practical substitute — the devotion is what matters.
