Definition
Karthika Masam is the lunar month following Deepavali — Karthikai in Tamil, Kartik in the north — kept across the Telugu and Tamil south as a month of lamps, and at the threshold it is the year’s most sustained stretch of lamp-centred drawing: a design each morning, most of them built to hold a light.
History
The month’s observance gathers several older strands — the lighting of lamps through a whole lunar month rather than a single night, the Monday fasts kept by many households, and the Karthigai Deepam festival that closes the season in the Tamil country. Threshold drawing tracks this shape rather than a single date: where Deepavali concentrates effort into one spectacular design, Karthika distributes it across thirty mornings, and the drawn form adapts by making the lamp its recurring subject.
Description
The design library shows the month’s two rhythms plainly. The dot-grid kolam continues as the daily form — Karthikamasam Special 8×8 Kolam, Karthika Somavaram Rangoli 13×7 — with the Somavaram (Monday) designs marking the fast days that structure the month. Alongside them sit designs whose subject is the lamp itself: Karthikamasam Diya Rangoli Designs 7×7 places diya forms inside the grid rather than beside it. The padi kolam — the stepped, rectilinear form kept for Fridays — appears here too, so the month layers a weekly cycle over a monthly one.
Cultural Context
A month of lamps makes the threshold a nightly rather than a daily surface. The drawing is made in the morning and is still there when the lamp is set into or beside it at dusk, so the design must survive a day of use and still frame a light — which is why the grid forms dominate over freehand ones here, and why lamp motifs recur where flowers might otherwise appear.
Regional Variations
The month is Karthika Masam in Telugu-speaking households and Karthikai in Tamil ones, and the drawn vocabulary shifts with the name: muggulu in Andhra and Telangana, kolam in Tamil Nadu, with the padi kolam and the Monday designs most strongly marked in the Tamil observance. The northern Kartik shares the lunar month and the lamps but not the threshold-drawing tradition in the same daily form.
