RAHU MANTRA IN RAHU KALAM

The best time to chant the Rahu mantra in the daytime is during Rahu Kalam (Rahu Kaal), a roughly 1.5-hour period daily that is specifically auspicious for pacifying Rahu. While Rahu, a shadow planet, is often worshipped at night, Saturday daytime (especially during Rahu Kalam) is ideal to reduce negative influences. 

Optimal Daytime Times

• Rahu Kalam (Daily): This is considered the most effective time during the day to chant to reduce negative energy. The specific time changes daily; you should check a local panchang (Hindu calendar) for that day's timing.
• Saturdays: Saturday is the most crucial day for Rahu and chanting during Rahu Kalam on a Saturday is highly effective.
• Early Morning (Dawn): Some practitioners suggest early morning for calm, focused chanting.
• Noon: The Rahu Gayatri mantra can be recited at noon. 

Key Guidelines for Chanting

• Mantra: The primary Beej mantra is: “Om Bhraam Bhreem Bhroum Sah Rahave Namah”., Aum Simhika Putray Namah.

• Duration: Often, it is recommended to complete 18,000 chants within 40 days for full effect.
