August 2026 Chandrashtama Dates: Calendar & Timings for All 12 Rasis

During August 2026, the global emotional tide is influenced by two critical outer planetary transits. First, Saturn remains retrograde in Revati nakshatra, which rules the deep subconscious, endings, and karma. This retrograde motion can bring unresolved anxieties and past emotional patterns back to the surface.

Second, on August 19, 2026, Jupiter moves into Ashlesha nakshatra. Ashlesha, governed by Mercury and located in the sign of Cancer, is associated with deep, protective, and sometimes defensive psychological processing. When Jupiter, the planet of expansion, transits this nakshatra, it amplifies these mental sensitivities.

For the three water signs (Cancer, Scorpio, and Pisces), this dual influence acts as an emotional amplifier. Their monthly Chandrashtama days in August will carry higher-than-usual friction. Minor issues might trigger intense emotional reactions. Recognizing your personal dates is the first step toward conscious pacing.

Here is the complete chronological calendar of Chandrashtama periods for all 12 Rasis. All times are displayed in Indian Standard Time (IST, GMT+5:30). If you live outside India, please convert these timings to your local timezone.

Krishna Janmashtami falls on August 15, 2026. Devotees traditionally observe a full fast—often a strict, waterless fast (Nirjala Vrata)—until midnight. However, this year, the festival directly overlaps with the Chandrashtama periods for two signs:

For Makaram, Chandrashtama is active from August 13 until it ends at 09:34 AM on August 15. For Kumbam, Chandrashtama begins exactly at 09:34 AM on August 15 and runs through August 17.

Because the eighth-house lunar transit naturally lowers your emotional stamina and physical resilience, going without water or food during this time is highly discouraged. Doing so is likely to trigger severe blood sugar drops, resulting in intense physical fatigue, brain fog, and heightened irritability—completely counteracting the peaceful, spiritual mindset required for worship.

Our Recommendation: If you are a Makaram or Kumbam native, please avoid strict water fasting on August 15. Instead, follow a blood-sugar-stabilizing Phalahar (fruit-based) approach. Consume fresh fruits, milk, curd, nuts, and light, non-grain preparations (such as sabudana or rajgira) at regular intervals. This maintains your vital energy, keeps your nervous system calm, and allows you to participate in prayers and meditation with absolute focus.

No matter what sign you belong to, you can optimize your productivity by aligning with these cosmic currents. During your Chandrashtama days, adopt these practical rules:

Double-check communication: Proofread emails and code commits twice. Take a brief pause before sending messages to avoid misunderstandings.

Defer high-stakes decisions: Postpone contract signing, major financial investments, or critical career shifts by 48 hours until the lunar tide shifts.

Focus on maintenance: Use these days to clean up your backlog, perform background research, organize files, and plan your next major moves.

Water Signs (Cancer, Scorpio, Pisces) special care: Because Jupiter in Ashlesha and Saturn retrograde in Revati amplify your sensitivities, prioritize 7-8 hours of sleep, stay well hydrated, and practice 5-10 minutes of daily grounding exercises or meditation.
