Karthika Masam is considered equally dear to Shiva and Vishnu. Lighting deepams, the pre-dawn river bath, the Karthika Somavaram vratam, vanabhojanam, Ksheerabdhi Dwadashi and Karthika Pournami together make it the most sacred month of the Telugu year. The Puranas say that even a single lamp lit with devotion in this month brings great merit.
Karthika is the eighth month of the Telugu lunar calendar. It begins on Karthika Shukla Padyami, the day after Ashwayuja Amavasya (Deepavali), and ends on Karthika Amavasya. The Moon is in Krittika nakshatra on its Pournami, which gives the month its name. It is the second month of Sharad ruthuvu. Check your regional panchangam for exact dates.
Why is Karthika Masam so sacred?
A month for both Hari and Hara
Most months are linked with one deity, but in Karthika both Shiva and Vishnu are worshipped. Mondays are special for Shiva and Ekadashi and Dwadashi for Vishnu, so the month is seen as celebrating the unity of Hari and Hara.
Damodara Masam
In the Vaishnava tradition Karthika is called Damodara Masam, recalling how Yashoda tied little Krishna to a mortar with a rope (daama). Devotees offer lamps remembering this leela.
End of Chaturmasya
Vishnu is believed to enter yoga nidra on Ashadha Shukla Ekadashi and awaken on Karthika Shukla Ekadashi (Utthana Ekadashi). After this the season of weddings and other functions picks up again.
Why is the Karthika deepam important?
The lamp is the symbol of Karthika. In the evening, families light deepams at the doorstep, at the tulasi kota, in the puja room and at temples. The lamp stands for knowledge removing the darkness of ignorance.
- Lamps are traditionally lit with sesame oil or cow's ghee.
- Some families keep an akasha deepam, a lamp raised high, through the month.
- Many homes light a 365-wick lamp on Karthika Pournami, believed to give the merit of a lamp for every day of the year.
- Floating lamps in banana-leaf cups on rivers and tanks is a beautiful custom.

What is Karthika snanam?
Bathing in a river, tank or the sea before sunrise during Karthika is called Karthika snanam. Devotees taking an early dip and floating lamps on the Godavari and Krishna is a sight unique to this month. Those who cannot go to a river bathe early at home while remembering Ganga.
Caution: Early-morning water can be cold and currents strong. Children and elders should avoid deep water; bathe only at safe ghats.
What is special about Karthika Somavaram?
Every Monday of Karthika is highly sacred for Shiva worship. Many people fast through the day, perform abhishekam and deeparadhana at a Shiva temple in the evening, and eat after seeing the stars. Some take only fruit and milk during the day. Fasting rules vary from family to family.
Health note: Pregnant women, elders, people with diabetes or other health conditions and those on regular medication should avoid strict fasting and follow a lighter observance after consulting their doctor. Devotion matters more than strain on the body.

Why is Ksheerabdhi Dwadashi special?
Karthika Shukla Dwadashi is Ksheerabdhi Dwadashi, also called Chiluku Dwadashi, linked with the churning of the ocean of milk. Vishnu is believed to come to the tulasi grove with Lakshmi on this day. In the evening families place an usiri branch beside the tulasi plant, worship tulasi as Lakshmi and usiri as Vishnu, and light lamps. Some families celebrate it as Tulasi kalyanam.
Vanabhojanam: a festival with nature
During Karthika, families and friends go to groves, worship under an usiri tree and share a meal together. The usiri tree is revered as a form of Vishnu, and the outing builds family bonds as much as devotion. A typical vanabhojanam goes like this:
- Choose a garden or temple grove with usiri trees.
- Worship the tree with turmeric, kumkum and flowers and light a lamp.
- Offer sattvic dishes such as pulihora, daddojanam and payasam as naivedyam.
- Eat together and spend time with games and songs.
- Leave the place clean and avoid plastic.
Common observances in Karthika
- Reading one chapter of the Karthika Puranam daily.
- Sattvic food; many families avoid non-vegetarian food.
- Deepa danam, anna danam and vastra danam.
- Visiting Shiva and Vishnu temples.
None of these is compulsory for everyone; follow them according to your health, ability and family tradition.
