Answers the timing question an agent has before it schedules anything against a regulated exchange: is the main session running, and if not, when does it start. Covers XETR, XFRA, XNYS, XNAS, XLON, XPAR, XAMS, XSWX, XTKS and XHKG with pre trading, main session, post trading, half days and the holidays of 2026 and 2027. Time zones are resolved through IANA names and Intl at the queried instant, never through a fixed offset to UTC, because summer time starts and ends on different dates in the Euro
