Why Your Festival Date Doesn't Match Your Cousin's

You look up Ekadashi. One website says Saturday. Your temple says Sunday. Your cousin in Hyderabad is already fasting.

Nobody is wrong. You've just met the Panchang.

The word means "five limbs," and it's the oldest working calendar most of us will ever use. Where a wall calendar tells you the date, a Panchang tells you what the sky is doing. That's why it can look like a foreign language until someone explains the five parts.

The moon's day

Start with the tithi, because this is the one that causes the arguments.

A tithi is the time the Moon takes to pull 12 degrees ahead of the Sun. There are 30 of them in a lunar month: 15 as the Moon grows, 15 as it fades. But the Moon doesn't keep office hours. A tithi can begin at 3:40 in the afternoon, run short or run long.

So when a tithi begins on a Saturday evening in India, it may still be Saturday morning in New Jersey. Add the common rule that the day belongs to whichever tithi is in force at sunrise, and your festival can land on a different date from your family's. Same sky. Different sunrise.

The other four

Vara is the weekday. It's the only limb that just repeats, and the only one you already know.

Nakshatra is the Moon's star group. The Moon's path is divided into 27 of them, and it moves through roughly one a day. If your grandmother asked which star you were born under, this is what she meant.

Yoga has nothing to do with a mat here. It's one of 27 divisions worked out by adding the positions of the Sun and Moon together.

Karana is half a tithi. It's the part most people never look at, and that's fine.

What you actually need

Forget the full page. For everyday life, three things are enough:

• The tithi, and when it ends
• The nakshatra, and when it ends
• Sunrise and sunset where you live

Then one more habit: always read a Panchang made for your own city. A printed one from Chennai is beautiful, and it's calculated for Chennai.

If you still get two answers, ask your temple, or do what your family has always done. North and South Indian calendars even count their months differently, so a mismatch doesn't always mean a mistake. Sometimes it's just two old traditions, both still going, in the same family group chat.
