Chandrashtama Days October 2026: All 12 Rasis, Exact Times
October begins in Purattasi and turns to Aippasi on the 18th, with Ayudha Puja and Vijayadasami following on the 19th and 20th — days many families keep for new beginnings, a child’s first lessons (Vidyarambham) and travel home. Chandrashtama windows do not pause for festivals, so the sensible move is to check your dates before the calendar fills rather than after.

2. How October breaks down
October 2026 contains 14 Chandrashtama windows across the twelve rasis. The longest belongs to Rishabam, running 60.8 hours.
2 rasis have two separate windows this month: Thulam, Vrichigam. Assuming the month is done once the first one ends is an easy mistake to make.
No rasi is skipped this month — every sign has at least one window.
3. Festivals in October 2026 and who is in Chandrashtama
Ayudha Puja (Saraswati Puja) — Monday, 19 October. Tools, books and instruments are set aside for worship, and many households keep the day for puja and rest rather than work. A window on this day costs little — the day is already a quiet one. In Chandrashtama on this day: Midhunam (18 Oct, 07:33 pm – 21 Oct, 07:00 am).
Vijayadasami — Tuesday, 20 October. Traditionally chosen for beginnings — Vidyarambham, the first day of a new job or venture, a new purchase. If your window falls here, the beginning can still be marked with the puja, and the practical step — the signature, the payment, the journey — taken once the window ends. In Chandrashtama on this day: Midhunam (18 Oct, 07:33 pm – 21 Oct, 07:00 am).
Festival dates: Drik Panchang (Chennai). Local observance can differ by a day, so confirm with your family’s practice.
4. Guidance for your specific rasi
Each rasi has its own October 2026 page with a calendar view, the window timings again in your own timezone, and month-specific practical guidance:
Mesha · Rishabam · Midhunam · Kadagam · Simmam · Kanni · Thulam · Vrichigam · Dhanusu · Makaram · Kumbam · Meenam
Where a festival date and your window overlap, nothing here asks you to skip the occasion. It is a reason to lighten the load around it — less travel, fewer commitments stacked on the same day, and rest where you can take it.
