01Five clocks, one day
One date on the wall calendar is five things in the panchang: a weekday, a lunar day, a lunar mansion, a Sun–Moon yoga, and a half-tithi. All five run simultaneously, each on its own rhythm. Together they give the day its texture — which is why no two Tuesdays are quite the same day.
02The five limbs
| What it is | What it colours | |
|---|---|---|
| Vara | The weekday, ruled by its planet — Monday is the Moon's day, Saturday is Saturn's. | The day's baseline temperament. |
| Tithi | The lunar day — one of 30, each spanning 12° of Sun–Moon separation. | Auspiciousness of undertakings; the layer festivals are pinned to. |
| Nakshatra | The Moon's mansion that day — one of 27. | The day's emotional texture; the key limb for muhurta. |
| Yoga | One of 27, computed from the sum of Sun and Moon longitudes in 13°20′ steps. | A subtle quality — a few yogas are traditionally avoided for beginnings. |
| Karana | Half a tithi — 11 types: 7 repeating "movable" and 4 fixed. | Fine-grained timing for starting an act. |
03From panchang to muhurta
Muhurta — electional astrology — is panchang reading in reverse: instead of asking what today is like, you search for a day whose five limbs suit the act. A marriage wants one combination, a housewarming another. Rahu kaal, choghadiya, and abhijit muhurta are all cuts of this same five-limbed day.
