Why the Panchang From India Gives You the Wrong Time in America
October 7, 2026 · 5 min read
Most Indian families in the US get their timings in one of three ways: a wall calendar printed in India, an image forwarded on WhatsApp, or a website that quietly defaults to New Delhi. All three look authoritative, and all three are worked out for someone else's sunrise.
Two kinds of numbers in a panchang
The five limbs of the panchang (tithi, vara, nakshatra, yoga and karana) look like calendar entries, but they are measurements of the sky. They come in two kinds:
- Moments that are the same everywhere. A tithi changes when the moon moves another 12 degrees ahead of the sun. That happens at the same instant all over the world: 2:02 AM in New York is 12:32 PM in Delhi. Converting these times between time zones is fine.
- Windows tied to your own horizon. Sunrise, sunset, Rahu Kaal, Abhijit, Choghadiya, Pradosh Kaal and the rising lagna are all local. Converting them from IST gives you nonsense, and using India's clock times as they are gives you an answer that is close but wrong.
Almost every real decision needs both kinds. The tithi tells you which lunar day it is. Your own sunrise tells you which of your calendar days that tithi belongs to, and your own horizon tells you which hours inside it are good.
Three ways it goes wrong
- Converting from IST. Delhi's Lakshmi Puja window on November 8, 2026 is 5:54–7:50 PM. Converted to Eastern time, that becomes 7:24–9:20 in the morning, nowhere near the sunset the window is built around.
- Copying India's clock time. Use 5:54–7:50 PM as-is in Boston and about two-thirds of that time falls after Boston's actual window closes at 6:33 PM.
- Getting the wrong day. Some festivals go to the day that has the right tithi at sunrise or in the afternoon. In 2026 that puts Govardhan Puja and Bhai Dooj a day earlier in the US than in India, and a calendar printed in India will show you the Indian dates.
Rahu Kaal: one rule, four answers
Rahu Kaal is one-eighth of the daylight hours, and the weekday decides which eighth. On Sunday it's the last eighth before sunset. On Sunday, November 8 that is 3:30–4:46 PM in New Jersey, 3:13–4:29 PM in Boston and 4:17–5:38 PM in Austin. In Delhi it's 4:09–5:31 PM. The rule is the same everywhere, yet the answers differ, and you can't get one from another by changing the time zone.
| Place | Sunrise | Rahu Kaal, Sun Nov 8 |
|---|---|---|
| New Jersey (Edison) | 6:35 AM | 3:30 – 4:46 PM |
| Boston | 6:26 AM | 3:13 – 4:29 PM |
| Austin | 6:50 AM | 4:17 – 5:38 PM |
| New Delhi | 6:38 AM | 4:09 – 5:31 PM |
What to do instead
- Take tithi start and end times from any reliable source and convert them to your time zone. That part carries over.
- Work out anything tied to sunrise or sunset for your own city, or use a source that does it for your city.
- When the date of a festival matters, check the date where you live instead of assuming it matches India's.
- Leave five to ten minutes of slack at both ends of a window. The tradition cares about the window, not the exact second.
The people and tools that used to answer "when?" for your family, the pandit and the panchang on the wall, were set up for a different horizon. The tradition still applies after you move. The arithmetic just has to be redone for the place you live now.
