Daily Timing
Rahu Kaal, Yamaganda and Gulika, Explained: The Three Daily Windows to Avoid
Rahu Kaal, Yamaganda and Gulika Kaal are the three inauspicious segments the panchang marks out daily — each about 90 minutes, placed by the weekday and local sunrise. This guide explains the eight-fold division, shows a real computed Delhi week, and states plainly what the rules do and do not ask you to avoid.
Open any panchang and three entries repeat day after day: Rahu Kaal, Yamaganda and Gulika Kaal. They are the classical day’s three avoidances — segments of roughly 90 minutes each during which the tradition asks you not to begin anything important. They are also the most mechanically regular things in the entire system: once you know the weekday and the local sunrise, you can derive all three with a ruler.
The eight-fold day
The computation starts by dividing daylight — sunrise to sunset — into eight equal parts. With a Delhi sunrise of 5:46 AM and sunset of 7:07 PM, each part runs about 100 minutes. The seven visible planets (Sun through Saturn) plus Rahu, the ascending node, then take those parts in a fixed weekday order:
- Rahu Kaal — Rahu’s segment. The strongest and most widely observed of the three; no new undertaking should be started in it.
- Yamaganda — the segment of Yama, lord of death. Avoided for beginnings, especially journeys.
- Gulika Kaal — the segment of Gulika, a son of Saturn. Avoided like its father’s hours; some paramparas paradoxically treat it as usable for repeating (not starting) certain works.
The segment each one occupies rotates by weekday. For Rahu Kaal the classical order — Monday the 2nd segment, Tuesday the 7th, Wednesday the 5th, Thursday the 8th, Friday the 4th, Saturday the 3rd, Sunday the 6th — is what produces the familiar “Monday morning, Sunday evening” pattern. Yamaganda and Gulika follow their own rotations through the same eight slots.
A real week, computed
Here is Bela’s engine output for Delhi, 3–9 August 2026 — sunrise-to-sunset division, Lahiri ayanamsa, no tables copied from anywhere:
| Day | Rahu Kaal | Yamaganda | Gulika Kaal |
|---|---|---|---|
| Monday 3 Aug | 7:25 AM – 9:06 AM | 10:47 AM – 12:27 PM | 2:08 PM – 3:48 PM |
| Tuesday 4 Aug | 3:48 PM – 5:28 PM | 9:06 AM – 10:47 AM | 12:27 PM – 2:08 PM |
| Wednesday 5 Aug | 12:27 PM – 2:07 PM | 7:26 AM – 9:06 AM | 10:47 AM – 12:27 PM |
| Thursday 6 Aug | 2:07 PM – 3:47 PM | 5:46 AM – 7:27 AM | 9:07 AM – 10:47 AM |
| Friday 7 Aug | 10:47 AM – 12:27 PM | 3:47 PM – 5:27 PM | 7:27 AM – 9:07 AM |
| Saturday 8 Aug | 9:07 AM – 10:47 AM | 2:06 PM – 3:46 PM | 5:48 AM – 7:27 AM |
| Sunday 9 Aug | 5:25 PM – 7:05 PM | 12:27 PM – 2:06 PM | 3:46 PM – 5:25 PM |
Check Thursday against the order above: Rahu takes the 8th segment, the last slice of daylight, 2:07–3:47 PM — exactly as listed. Once you see the mechanism, the panchang stops looking like decree and starts looking like arithmetic.
What to avoid in them — and what not to worry about
The classical texts are precise about scope: these windows govern beginnings. Do not schedule the first signing, the griha pravesh entry, the wedding muhurat, the departure of an important journey, or the launch of a venture inside them. Work already in motion — the commute, the shift, the ongoing construction — continues; the rule is about seed moments, not about living in fear of the clock.
Two further clarifications practitioners give every week:
- They are local. The division starts at your sunrise, so the windows shift with geography and season — Delhi’s Monday Rahu Kaal is not Mumbai’s. Bela’s city panchang pages compute them per city; the app does it for your exact coordinates.
- They are one layer, not the whole election. A moment that avoids Rahu Kaal is not automatically shubh — it has merely cleared the first gate. Tithi, nakshatra, yoga, karana and Panchaka still apply, which is why the full muhurat lists show ten rules per date rather than one.
Durmuhurtam: the fourth mark on the page
Our panchang also prints Durmuhurtam — one or two short daily segments computed from the weekday and sunrise that the muhurta texts single out for avoidance in the same way. It is less famous than Rahu Kaal but enforced inside Bela’s engine with equal strictness: any window overlapping it is disqualified from the computed muhurat dates.
The takeaway is simple. These three windows are the daily hygiene of Vedic timing — mechanical, local, and easy to check. Check them before you schedule anything that matters; do not let them rule anything that does not. Today’s windows for your city are on the panchang page, and the definitions of every term live in the learn hub.
Your moment, computed for you.
Generic lists clear the universal rules. The Bela app recomputes every window for your exact city and applies Tara Bala and Chandra Bala against your own birth star — the personal layer no article can.
