First Friday is not a festival with a gate, a programme or a headline act. It is a standing agreement: on the first Friday of the month, the arts venues along Nuʻuanu Avenue, Hotel Street, Bethel Street and Pauahi Street open late, most of them hang new work, and everyone walks between them. Some bars put on music. A few shops stay open. That is the whole format, and it has been running long enough to be the default Friday night out downtown.
Two things follow from having no central organiser. The first is that nothing is ticketed — the galleries are free, and you only spend money if you want a drink or dinner. The second is that the line-up genuinely varies month to month, and any guide claiming a fixed list is guessing. Below we have separated the venues whose own websites publish their First Friday hours from the ones that merely appeared on the community calendar.
We also could not find any official source saying the streets are closed to traffic, so plan on normal roads and normal crossings.
