23:27
NOT NOW
Checking your clock…
In Luxembourg the local lexicon for a late ping is not 'async' — it is a flare. Banking and EU hours. Cross-border commuters vanish at 17:30 sharp. The polite window around Kirchberg is 08:00–18:00 local. Winter daylight collapses early, so an afternoon ping can already feel like night. Ping their late morning unless you already share an on-call rota. Luxembourg still shifts with daylight saving (UTC+1 in January, UTC+2 in July).
