Pride is usually in June because that's when Stonewall took place. Coincidentally, in the US, that's also the month in which same sex relationships were legalized (2003), same sex marriage was legalized (2015), and lgbtq people received the right to hold a job (2020).
That said, some cities will hold their pride celebrations at different times either because of a local event involving the lgbtq population or because they want to boost their numbers by having pride when big cities aren't.
