Choghadiya in Mississauga today

Mississauga's Hindu households cluster in the north and east — Malton, Derry, Meadowvale, Heartland — within a short drive of both the Brampton mandirs and the Etobicoke BAPS campus, which is why the city's own institutional footprint looks smaller than its population suggests. The Hindu Heritage Centre on Kennedy Road carries the weddings, the Navratri garba and the paath bookings. A lot of practice here is airport practice: Pearson sets the household clock, and shift workers coming off a red-eye routinely fix an Ekadashi to whichever date their body thinks it is. The parana is announced after the Mississauga sunrise, and in the second half of the year that is a full civil day behind the tithi on an Indian calendar.

Eastern Time with DST, same dates as Toronto and Brampton. Mississauga's sunrise falls between the two, and the city is long enough north to south that the Lake Ontario horizon at Port Credit and the Malton skyline near Pearson are not identical — this page uses the city centre coordinates.

  The city's main hall and mandir; weddings, Navratri garba and satyanarayan katha booked against the Ontario civil calendar, with muhurat windows quoted in Eastern Time.

• Malton and Derry Road satsang belt

  Punjabi and Gujarati mandals meeting in rented halls and homes around the airport. Timings circulate on WhatsApp; the reliable ones name Eastern Time, and the ones that quote a bare hour are usually copying an Indian source.
