What is Raahu Kaal
After violet, there is another group of rays called "ultraviolet" rays which are not visible to naked eyes. If we divide the daytime of Sunday into 8 parts of 1.5 hours each, this will be the order in which the colored rays will occur.
The timing of the ultraviolet rays when they fall on Earth are called as Raahu Kaalam and since they are not visible, they are considered as inauspicious. The following table will clarify things properly.
Ancient Tamil Hindu named the period of " Ultraviolet " rays as "RAAHU KAALAM".
Semi Rational people like most of us need not get scared by Raahu Kaal. As far as possible, they may remain at home or office and indulge in ethical deeds. If at all, it is essential to travel during this period, they may chant Raahu Kaal Durgaa Ashtakam or Durgaa Sapt Shlokee. Idea is not to get exposed to the ultraviolet rays being emitted at that time.
The sequence of colors of rays at night is exactly reverse of the sequence in
the day, as we see in a mirror. So, there is Raahu Kaalam at night also. Nobody
takes it Seriously as most of us are asleep during that period.
Another reason why Raahu Kaal is more effective on Sundays and Mondays is Horaa factor. Horaa (means planetary hour, such as on Sunday the Horaa is of Soorya), Horaa of Saturn coincides with Raahu Kaal on Sunday and Monday.
On Sunday, Raahu Kaal is in the last segment of the day - 1/8th segment,
approximately 90 minutes, before sunset.
JHora software by default calculates Raahu Kaal by taking the whole day (from one sunrise to next sunrise). Therefore Raahu Kaal of JHora appears different from common Panchaang and almanacs. In practice, Raahu Kaal calculated by real day-and-night elongation works better.
Raahu is a disguise and misleading form of Raakshas in Devtaa form at the time of distribution of nectar between Devtaa and Raakshas. Raahu is a deceptive form and is considered astrologically "mentally low". Nodes' importance is associated with eclipses, which are considered as most inauspicious. Likewise Raahu Kaal is also the time meant to leave or to not attempt anything auspicious, as this time misleads and makes to commit blunders (due to mental vibrations) that arise out of cosmic universe.
We have astrologically "Ayanaansh" factor as the movement of planets is not uniform and wobble during rotation. This provides for correction factor and is uniform mostly varies by a minute from year to year. This of course, is an issue linked to scientific observation. The importance of Raahu Kaal to this scientific aspect and for day to day purpose, yet statistical purposes is not confirmed yet. Astrologically the concept of Horaa relating to the weekdays in relation to the planet for that particularly day taking hold of the events that follow those who follow Soorya Maan have more importance to Raahu Kaal than those adopted to Chandra Maan.
This is also true that the classical texts have not thrown much light on the subject except that after sunset "Raahu Kaal" is not relevant. Nearest time is before sunset is noticed to be on Tuesdays (3 PM to 4.30 PM). Starting early in the morning at 4.30AM, Raahu is stated to be in East directionally. He is identified (directionally) as in East during Sunday and Thursday, in West on Tuesdays, in North on Wednesday and Saturday and in South on Monday and Friday.
It is understood to impact mental vibrations based on location/direction, when is supposed to be active during day time. It is prone during the Raahu Kaal time for the human beings to be inconsistent and tendency to commit errors and mistakes that leads to increased worry and anxiety. It is suggested not to undertake important and auspicious work. Night time that is after sunset, is time for rest and be free from anxieties till sunrise. Raahu Kaal is therefore considered as not much relevant.
This method of knowing auspicious time for traveling, is more common in Southern India. Raahu Kaal is the time period of the day when traveling is not auspicious. A Day (from sunrise to sunset) is divided by 8 and the resultant period is called one Kaal. Thus there are 8 Kaal of different durations according to the duration of the daytime. Each day, from Sunday to Saturday, there is a different Kaal which is inauspicious for traveling. Raahu Kaal differs from day to day of the week but fixed times. One can calculate it counting on the knuckles of the hand with his fist kept closed. Raahu Kaal is observed more in the Southern part of India than elsewhere.
How to calculate Raahu Kaal is given below.
(1) How to Calculate the Raahu Kaal
There is no Raahu Kaal during the first segment of any weekday.
Since the Raahu Kaal is dependent on the Sun-rise and Sun-set times of your particular location, you must calculate it for each day using the method given below. Three examples with different sunrise and sunset timings:
Just remember this phrase
M(other) - 7:30 - 9:00 - MONDAY
Assuming that the sunrise is at 6:00 am Raahu Kaal starts at 7:30 am on Monday and each segment is of 1hr 30mins.
(2) How to Calculate the Raahu Kaal in South India
Otherwise, Raahu Kaal (in Tamil Paksh) is good in some cases, like who has evil Yog in his chart but it is good for his particular chart, he can benefit in Raahu Kaal, like Gand Yog, such people can do any good venture during Raahu Kaal especially when Raahu is having aspect of Lords such points in their natal chart (may be Yog with such planets, or Drishti of such planets, or Raahu is indicating such points (Raahu Nakshatra). In such cases Raahu Kaal is good for them, while in other cases it is neutral, Raahu Kaal should be calculated on the proportions of day according to Din Maan. Din Maan is the duration of the day time between sunrise and sunset. It is more applicable to Northern side of the world whereas in South India there is no big difference between the duration of day and night, especially in Tamil Naadu, Kerala and Sri Lankaa as there day and night are almost equal being near to Equator.
