In many Nepali and Indian homes you will still hear it before a journey or an important call: “Wait — it’s Rahu Kaal.” Choosing a good moment (muhurat) for a beginning is one of the oldest parts of Jyotish. You do not need an astrologer for everyday timing; you only need to understand how the day is divided.
The day is split into eight parts
For Rahu Kaal, Yamaganda and Gulika Kaal, the daytime — from sunrise to sunset — is divided into eight equal parts. Each part is a little over an hour and a half when the day is about 12 hours long, shorter in winter and longer in summer.
Each weekday gives one of these eight parts to Rahu:
| Day | Rahu Kaal is the… | If sunrise is 6:00 and sunset 18:00 |
|---|---|---|
| Sunday (Aaitabar) | 8th part | 16:30 – 18:00 |
| Monday (Sombar) | 2nd part | 7:30 – 9:00 |
| Tuesday (Mangalbar) | 7th part | 15:00 – 16:30 |
| Wednesday (Budhabar) | 5th part | 12:00 – 13:30 |
| Thursday (Bihibar) | 6th part | 13:30 – 15:00 |
| Friday (Shukrabar) | 4th part | 10:30 – 12:00 |
| Saturday (Shanibar) | 3rd part | 9:00 – 10:30 |
Because sunrise and sunset change through the year and from city to city, the real times shift every day. Rahu Kaal in Kathmandu and Rahu Kaal in Dubai on the same date can be more than an hour apart on the clock.
What Rahu Kaal is — and is not
Rahu is the shadow planet of confusion, obsession and the unexpected. Tradition advises against starting something important in Rahu Kaal: signing an agreement, beginning a journey, opening a shop, a first day at work, a puja for a new venture.
It is not a time of danger. Work that is already underway can simply continue; there is no need to stop your day. And some practices, such as prayers to Durga or Rahu’s own shanti puja, are traditionally done in Rahu Kaal.
Yamaganda and Gulika
Two more daily periods use the same eight-part day:
- Yamaganda (ruled by Yama) is also avoided for new beginnings.
- Gulika Kaal (Saturn’s son, Gulika) is said to make whatever begins in it repeat — fine for things you want more of, poor for things you do not, such as debts or funerals.
Abhijit muhurat: the midday window
Abhijit muhurat is the eighth of the fifteen muhurtas of daytime — a window of about 48 minutes around local noon. It is traditionally considered strong enough to support most beginnings when no other muhurat is available.
The seven Choghadiyas
Families in North and West India often use Choghadiya for quick decisions. The day (sunrise to sunset) and the night (sunset to next sunrise) are each split into eight periods, and each period takes one of seven names:
- Amrit (Moon) — the best of all, good for every beginning
- Shubh (Jupiter) — auspicious, especially for ceremonies and learning
- Labh (Mercury) — gain, good for business and study
- Char (Venus) — moving, good for travel
- Udveg (Sun) — anxiety, best avoided for new work
- Rog (Mars) — disease and conflict, best avoided
- Kaal (Saturn) — loss, best avoided for beginnings
The sequence starts with a different Choghadiya on each weekday. On a Sunday, for example, the day begins with Udveg, then Char, Labh, Amrit, Kaal, Shubh and Rog.
Putting it to use
- Open today’s Panchang and choose your city.
- Avoid Rahu Kaal, Yamaganda and Gulika for anything you are starting.
- Pick an Amrit, Shubh or Labh Choghadiya — or Char for travel.
- If nothing fits, Abhijit muhurat around midday is a good fallback.
For life’s biggest beginnings — a wedding, griha pravesh, a business launch, a naming ceremony — a proper muhurat also takes the tithi, nakshatra, your own chart and Moon sign into account. For those, ask me to find a date that suits both the day and you.
