I'm a Tamil guy with close friends in the Telugu community. We all grew up watching our families check the panchangam every morning before starting a journey, planning a wedding date, or just knowing when to avoid Rahu Kalam.
When I moved abroad, I noticed that the calendars back home weren't quite right for us. The printed almanacs and most online calendars use fixed Indian timings. But Rahu Kalam in Hyderabad and Rahu Kalam in London are not the same. The calculations depend on when the sun rises and sets at your location, and that changes depending on where you are in the world and what time of year it is.
Most of my friends across the South Indian diaspora — Tamil, Malayalam, Telugu — still follow these traditions wherever they live. They check the shubha vela before a job interview in New York. They avoid Rahu Kalam when signing a lease in Sydney. But they were using timings calculated for a city they no longer live in.
The panchangam calculations — tithi, nakshatra, yoga, karana — are done live in your browser using a professional-grade astronomy engine. No data is stored on our servers. Nothing is sent back to us.
There are three sites covering Tamil, Malayalam, and Telugu, because the South Indian diaspora is not one community. It's many, with different calendars, different festivals, and different traditions. Each site is built for its own audience.
This is a small project. It's not perfect. But it's built with genuine care for a community that still finds meaning in these ancient calculations, wherever in the world they've ended up.
