Navratri (Day 1) 2027 in Mumbai

Local observance date: Friday, 1 October 2027. This differs from the India (Delhi) anchor (Thursday, 30 September 2027).

Sunrise: 06:30
Sunset: 18:28
Tithi at sunrise: द्वितीया (ends ~03:35)
Nakshatra at sunrise: Chitra
Ghatasthapana day: 06:30 (IST (India Standard Time))
Coordinates: 19.0760°, 72.8777° · Asia/Kolkata

Kshaya tithi note: This tithi was skipped between two sunrises at this location. An alternate observance date (Thursday, 30 September 2027) is defensible in some traditions — we show both in our Ekadashi pages; confirm with your sampradaya.

Rule used: Ashwin Shukla Pratipada — first day of Navratri when Pratipada tithi prevails at local sunrise.

How these timings are calculated

Calculated using Daanyam's stated Panchang convention: Smarta purnimanta month labels, tithi sampled at local sunrise (Pradosh festivals use local sunset). India anchor dates use Delhi coordinates (28.6139°N, 77.209°E). Diaspora cities use catalog coordinates and IANA timezones including daylight saving where applicable.

Ephemeris: astronomia (sync) with Lahiri ayanāṃśa for nakshatra; Astro Engine when enabled for month strips.

Sunrise/sunset: NOAA-style solar approximation at observer coordinates.
