2026 festival guide · verified against the Rashtriya Panchang
Karthigai Deepam falls on 24 November 2026. Understand the Krittika–Purnima overlap, Bharani Deepam, Maha Deepam and regional observances.
Short answer
Karthigai Deepam is observed on Tuesday, 24 November 2026. The Rashtriya Panchang lists Kartika Shukla Purnima until 8:24 p.m. and Krittika Nakshatra until 11:25 p.m. in its standard day entry. Local sunrise, nakshatra boundaries and temple programmes should still be checked for the place of observance.
Key takeaway: The festival is anchored in the Tamil month of Karthigai and Krittika Nakshatra. Bharani Deepam and the evening Maha Deepam are related observances, not two names for the same lamp-lighting moment.
The 2026 date at a glance
Karthigai Deepam is one of the major lamp festivals of Tamil tradition. In 2026 the civil date is Tuesday, 24 November. The national panchang entry for that date brings together Kartika Purnima and Krittika Nakshatra, the combination from which many readers recognise the observance.
A festival date is not produced by the Gregorian calendar alone. Panchangas evaluate a lunar tithi and a nakshatra against sunrise, local time and the rule followed for that observance. That is why a reliable guide gives the governing calendar elements as well as a date, and why a city-specific panchanga can show slightly different clock times.

What Bharani Deepam and Maha Deepam mean
At Arunachaleswarar Temple in Tiruvannamalai, Bharani Deepam is traditionally kindled before dawn inside the temple. Its name refers to the Bharani nakshatra prevailing in the preceding part of the observance, not to a separate annual festival unrelated to Karthigai.
Maha Deepam is the great flame lit in the evening on Arunachala hill. Devotees understand the column of light through the Arunachala tradition of Shiva as limitless fire. The temple ritual, the hilltop beacon and rows of household lamps are therefore connected expressions at different scales.
Exact access arrangements, procession routes and lighting times are operational matters announced by temple and district authorities. Travellers should treat social-media posters as provisional until an official programme is available.
Karthigai Deepam and Kartik Purnima are related, not identical
North Indian calendars commonly foreground Kartik Purnima, the full-moon tithi. Tamil calendars foreground Karthigai month and the Krittika star. These systems can point to the same civil day, but their naming logic is not identical. Translating every regional name into “Kartik Purnima” erases the nakshatra-based Tamil framing.
The same date may also carry other regional observances. A careful calendar should display them side by side and state which rule generates each label instead of implying that one name replaces all the others.
How families commonly observe the evening
- Clean and prepare lamps before sunset, following the fuel and wick custom used in the household.
- Place lamps safely at the threshold, courtyard, balcony or prayer space, away from fabric and children.
- Light lamps after sunset according to family practice; temple timings do not automatically become a household muhurta.
- If visiting Tiruvannamalai, use official crowd, transport and fire-safety instructions.
- Treat the lighting as a devotional custom; avoid claims that the flame predicts personal events.
Why spelling varies online
Karthigai, Karthikai and Karttikai are English transliterations of Tamil forms. Deepam and Dipam likewise represent the same word through different transliteration choices. Searchers using “Karthikai Deepam 2026” are normally looking for the same festival covered here.
Krittika is the Sanskrit nakshatra name. Karthigai is also the Tamil star and month name. Similar spelling does not make the astronomical segment, solar month and festival label interchangeable; context tells the reader which meaning is intended.
