We def have pride “month” in Australia.

However, most cities have pride festivals at other times of year like my city had a bunch of events over 2 weeks in Febreuary.

IDK why it’s a whole month? You’re right it’s unusual. We celebrate different sports for different periods of time. IDK if that counts.

People refer to “Christmas time” or “over christmas” as a vague period of several weeks. “We’re going to visit mum and dad over christmas” implies a week or more.
