At the start of the year 2022, Ketu had been transiting the Zodiac sign Scorpio. On April 12, 2022, Ketu will change signs and move to Libra, while Rahu will move from Taurus to Aries. Compared to other planet lords, Rahu and Ketu move in the counterclockwise direction around the chart. Hence when it changes signs, Rahu and Ketu move to the signs that come before their present sign instead of the sign which comes after them, as other planets do.

Rahu Ketu's transit period is 18 years. Rahu and Ketu are lunar nodes. They are energy centres formed by crossing if Moon's orbit with that of Earth's. Due to their tremendous influence on life on Earth, both are given the status of planets. They are placed 180 degrees apart in the chart and go around all the 12 signs in the chart once every 18 years.

Ketu is positioned in Scorpio as of the beginning of the year 2022. On April 12, 2022, it will change signs and get positioned at Libra, where it will remain till October 30, 2023.

It takes Rahu 18 months to transit a zodiac sign of 30 degrees. In all, it takes Rahu 18 years to cover all 12 signs of the zodiac once.

Like Rahu, Ketu also takes 18 months to cover a Zodiac sign spanning 30 degrees in the chart. Rahu and Ketu are positioned in diametrically opposite signs in the chart. Both move in the anti-clockwise direction across the chart.

Due to their shadowy nature, Rahu and Ketu's influences are felt on a spiritual level rather than the physical level. Rahu causes a person to become obsessed with something, while Ketu inspires the feeling of detachment. To please Rahu, one should chant the bheej mantra Om Bhram Bhreem Bhroum Sah Rahave Namah 18,000 times. Fasting on Saturdays and donating food to the poor will help. Keeping fennel seeds beside your pillow is another way. To please Ketu, chant Ketu bheej mantra Om Shram Shreem Shroum Sah Ketave Namah 17,000 times. Observe fasts on Tuesday and Saturday. Donate blankets and help the old and needy.

Rahu and Ketu are lunar nodes formed by the intersection of the Moon's orbit with that of Earth's. Rahu is the ascendant node, while Ketu is the descendent node. As per ancient history, Rahu and Ketu represent the head and body respectively of the celestial snake who secretly drank the divine nectar Amrit and who was in turn beheaded by Lord Vishnu using his Vishnu Chakra. Since the demon had already drunk the Amrit, he did not die; instead, he lived on with a separate head and body called Rahu and Ketu, respectively. In the chart, both are placed 180 degrees apart from each other and act in unison upon a person. Since they are shadow planets, their effects are more spiritual than physical. Both represent karmic deeds and are points that connect this life with past lives. Though both are considered equal, Rahu has more prominence in Vedic literature than Ketu

Though the influence of Ketu is more spiritual than physical, ill effects of Ketu can be felt physically also. Skin disease, joint pain, hearing loss, problems with the spine etc., are some of the physical ill-effects associated with Ketu. Psychological problems associated with the ill effects of Ketu include addiction to intoxicants, feeling of insecurity and lack of motivation. Some people also fall prey to superstitious beliefs under the ill effects of Ketu

Ketu in the 12th house is considered important. It turns on the spiritual calling of the person. The 12th house is the house of karma, so, with Ketu in the 12 house, the person will have to work hard and overcome many obstacles. But the hard work will be rewarded, and the person will be able to lead a meritorious life. There may be some illnesses in the eye and abdomen region. The person may experience love failures and feel detachment from worldly life. 12th house is also the house of moksha. The presence of Ketu in this house will inspire the person to work towards achieving peace and enlightenment in life.
