Night-desk rule for Cardiff: if you would not ring a bell in Central Cardiff at that hour, do not Slack. Senedd hours. Friday after 16:00 is already the weekend in a way London pretends not to notice. Cardiff still shifts with daylight saving (UTC+0 in January, UTC+1 in July). The polite window around Central Cardiff is 09:00–17:00 local. Put the timezone in the invite title so nobody has to do the math in public.
