Today's Rahu Kaal

Rahu Kaal, Yamaganda Kaal and Gulika Kaal are equal daylight eighths that shift with sunrise and sunset. Brahma and Abhijit track the day's twilight and midday. Amrit Kaal and Varjyam depend on the moon's nakshatra, so they can fall at night or, on some days, not occur at all. Those cells show a dash.

A quick guide to every window marked on the dial above: which are auspicious, which to avoid, and what each is traditionally used for.

Rahu Kaal (also spelled Rahu Kalam) is a recurring stretch of about ninety minutes each day that Vedic tradition marks as inauspicious for beginning anything important. It takes its name from Rahu, the shadowy north lunar node, whose influence is held to cloud judgement and undo fresh starts. Like Choghadiya, it needs no birth chart: it is read entirely from the day's sunrise, sunset and the weekday. Most people simply wait it out before signing a deal, setting off on a journey, holding a ceremony or making an important purchase, and resume once the window has passed.

Of all the daily inauspicious periods, Rahu Kaal is the most widely observed across India and is checked before weddings, housewarmings, new ventures, travel and big purchases. The reasoning is practical as much as astrological: a single, easy-to-remember window that anyone can avoid without an astrologer keeps an important act clear of an unfavourable hour.

Rahu Kaal sits alongside two sister windows, Yamaganda Kaal and Gulika Kaal, that are read the same way from the weekday and sunrise. Of the three, Rahu Kaal is treated as the most significant, which is why it has its own page and is usually checked first.

Rahu Kaal is built from the daylight span alone. The time from sunrise to sunset is divided into eight equal parts, and one of those parts, fixed by the weekday, is Rahu Kaal. Because daylight length changes through the year and from place to place, each part is rarely exactly ninety minutes, and the clock time of Rahu Kaal shifts with your city's sunrise and the season.

Which of the eight parts is Rahu Kaal depends only on the weekday. It never falls in the very first part after sunrise. Monday takes the second part, Saturday the third, Friday the fourth, Wednesday the fifth, Thursday the sixth, Tuesday the seventh and Sunday the eighth and last. That is why the same page recomputes the window, along with the sun and moon times, the moment you switch your city or step to another date.

Which of the eight equal parts of daylight Rahu Kaal occupies on each weekday. The exact clock time still depends on your location's sunrise and sunset.

Counting the eight parts from sunrise. The first part after sunrise is never Rahu Kaal.

Rahu signifies confusion, illusion and sudden reversals, so the tradition holds that anything begun under its hour carries a shadow: outcomes that disappoint, stall or unravel. The window is therefore reserved for what is already in motion or purely routine, and kept clear of fresh commitments and irreversible steps.

The caution applies only to beginnings. Rahu Kaal does not stop work already underway, daily chores, or anything urgent and unavoidable; it simply asks you not to start something new and lasting in that hour.

These are the new beginnings and important acts most people hold back until Rahu Kaal has passed:

• ✕Starting a new business, venture or job
• ✕Weddings, engagements and other ceremonies
• ✕Setting off on a journey or long travel
• ✕Buying property, vehicles, gold or other major purchases
• ✕Signing contracts, agreements or financial deals
• ✕Housewarming (griha pravesh) and laying foundations
• ✕Beginning education, training or an important first lesson

Rahu Kaal restrains only new beginnings. These are commonly considered fine:

• ✓Daily routine, work already underway and ongoing duties
• ✓Urgent, unavoidable or emergency tasks
• ✓Worship, prayer, chanting and Rahu-related remedies
• ✓Routine travel you take every day, such as a daily commute
• ✓Study, practice and revision that is already in progress
• ✓Eating, rest and ordinary household activity

For weddings, housewarmings, new ventures and other milestones, an auspicious muhurat is chosen, and the main test is that it does not overlap Rahu Kaal. Even a strong Choghadiya or a good Hora is usually dropped if it falls inside Rahu Kaal, because the shadow of the hour is held to outweigh the benefic window.

Checking takes only a moment: read today's Rahu Kaal for your city, then pick a time outside it. Because the window moves with your location and the date, the safest habit is to look it up fresh for the exact day and place of the event rather than relying on a remembered time.

Rahu Kaal is one of three inauspicious daylight windows read the same way from the weekday and sunrise. Yamaganda Kaal, linked to Yama, is likewise avoided for new work; Gulika Kaal, tied to Saturn's son Gulika, is the gentlest of the three and is even considered supportive for a few specific acts. The dial above marks all of them, alongside the auspicious Brahma Muhurta, Abhijit Muhurta and Amrit Kaal, so you can see at a glance which parts of the day to favour and which to leave alone.
