Onam 2026 falls on Thiruvonam — Friday 28 August 2026 — and the global Malayali diaspora will celebrate wherever they live. This guide gives verified local timings for the Onasadya lunch, Kerala Samajam events, and community Pookalam competitions across the seven biggest Malayali destinations: USA, UK, Canada, Australia, Singapore, Malaysia and UAE.

Thiruvonam Local Time — When to Serve the Onasadya

Traditional Onasadya is served at midday (11 AM to 1 PM) on Thiruvonam. In local time zones:

  • USA — Eastern (New York, Boston, Atlanta): Thiruvonam Sadya window is Fri 28 Aug ~11:00 AM ET.
  • USA — Central (Chicago, Dallas, Houston): Fri 28 Aug ~11:00 AM CT.
  • USA — Mountain (Denver, Phoenix): Fri 28 Aug ~11:00 AM MT.
  • USA — Pacific (Bay Area, LA, Seattle): Fri 28 Aug ~11:00 AM PT.
  • UK (London, Leicester, Birmingham, Manchester, Coventry): Fri 28 Aug ~12:00 PM BST.
  • Canada (Toronto, Brampton, Mississauga, Vancouver, Calgary): Fri 28 Aug ~12:00 PM local.
  • Australia — Sydney / Melbourne / Brisbane: Sat 29 Aug morning (Kerala Thiruvonam falls in AEST overnight; most communities defer Sadya to Sat 29 lunch).
  • Australia — Perth: Fri 28 Aug ~1:30 PM AWST.
  • Singapore: Fri 28 Aug ~1:00 PM SGT.
  • Malaysia: Fri 28 Aug ~1:00 PM MYT.
  • UAE (Dubai / Abu Dhabi): Fri 28 Aug ~10:00 AM Gulf Time.
  • New Zealand (Auckland / Wellington): Sat 29 Aug morning.

Nakshatra-based festivals do not have a single global timing — the tradition is to celebrate when Thiruvonam nakshatra is active in your local sky. When in doubt, follow the Kerala date and celebrate the Sadya on your local Friday lunch (or Saturday for Australia / NZ).

Australia — Community Onam 2026

Australia's Malayali community is one of the fastest-growing in the world. Because of the AEST time difference, most Sydney/Melbourne/Brisbane Sadyas are held on Saturday 29 August 2026 — the Kerala Thiruvonam falls overnight for Eastern Australia.

Celebrating Onam at Home Abroad — Family Checklist

If you can't reach a community event, host a home Onam:

  • Lay a simple 3-ring Pookalam at the entrance — rose petals + marigold + jasmine work worldwide.
  • Prepare a 10-dish Sadya (see our full menu guide) on a large plate if banana leaves are unavailable — Kerala grocery imports leaves in most major NRI cities.
  • Watch a live Kerala Onam telecast (Manorama / Mathrubhumi / DD Malayalam) with the family.
  • Video-call family in Kerala at Sadya time — the Thiruvonam ritual is shared across time zones.
  • Light a diya at the Pookalam centre; place a small Onathappan (or paper substitute).
  • Serve payasam — Ada Pradhaman, Palada, or Semiya — even if you only make one dish.
