National Chicken Wing Day is July 29. It traces back to Buffalo, New York, which proclaimed July 29, 1977, Chicken Wing Day to honour the Anchor Bar, where Buffalo wings were first served. It is mostly a US promotion, and US wing chains mark it with free-wing and discount offers at their US locations.
Promotions in US news coverage do not automatically apply at Canadian locations of the same chain, so check the chain's Canadian site or app. In Canada, the deals that matter most on July 29 are regular wing nights: many pubs and sports bars price wings by the piece or by the pound on a set weekday, so the day of the week decides what is on.
Wing deals usually come with conditions: dine-in only, a drink purchase, a minimum order of 8 or 10 wings, or a limited choice of flavours. Prices are per wing or per pound before tax.
