Hindu festival timings by city — 2027
Observing Diwali, Holi, or Navratri abroad? These timings are calculated for each city's latitude, longitude, and timezone — not simply converted from IST. Browse US, UK, Canada, and Australia metros first, then compare with India anchors.
Why Hindu festival timings change by location
Hindu festival dates follow the Panchang — a location-dependent calendar. A tithi (lunar day) begins and ends at a precise astronomical instant, but which civil date you observe depends on whether that tithi is active at your local sunrise (or at local sunset for some evening festivals).
Converting an India timetable to another timezone does not work: sunrise in New York is not Delhi minus 10.5 hours as a calendar rule. Timezone and daylight saving change how absolute tithi boundaries map onto local clock time — and can move the observance to an adjacent Gregorian day.
This index evaluates Panchang conditions at each city's coordinates. When every city shares Delhi's date, we show that. When Sydney or Los Angeles shifts by a day, we show that too.
Cities that differ from India's civil date

Not in this index yet
- Maha Shivaratri— Nishita (midnight) observance rule is not yet implemented in the production resolver; India date is Drik-sourced on the festival page.
- Onam— Thiruvonam follows solar Chingam / Kerala nakshatra conventions not covered by the tithi rule engine.
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.

Common questions
- Are these just IST times converted to my timezone?
- No. Each city recomputes tithi at local sunrise (or sunset for Pradosh observances) using that city's coordinates and IANA timezone. A festival can legitimately fall on a different civil date than Delhi.
- Which cities are included?
- Major diaspora metros across the US, UK, Canada, Australia, UAE, Singapore, and Malaysia, plus Delhi, Mumbai, Bengaluru, and Auckland for comparison. Open a city cell for the local date and observance window.
- How should journalists cite this dataset?
- Cite Daanyam's Global Hindu Festival Timing Index with the festival name, year, city, and the page URL. Download the CSV for the full matrix. Methodology and engine provenance are listed on each page.
