There are late sittings in a lot of jurisdictions. Australia goes until 9:30 p.m. New Zealand's House of Representatives on Tuesdays and Wednesdays sits from 7:30 p.m. until 10 p.m. The U.K. sits from 2:30 p.m. until 10:30 p.m. on Mondays. So, night sittings still exist in a number of jurisdictions, although all the provinces appear to more or less adjourn by 6 p.m.
On February 16th, 2016. See this statement in context.
