The trading day, where you are.

The “sessions” of the foreign-exchange market are conventions: the business days of Sydney, Tokyo, London and New York, laid end to end. Between them they cover almost the whole of a weekday. The stock exchanges are different: each is a venue with published hours.

Every time on these pages is worked out from the same timetable as this site’s clocks, for one or two named reference cities in the region and, on the dial, for your own time zone. The tables show two days, one in January and one in July, because the hours move when the clocks change.

Each guide ends with a list of questions about tax to take to a qualified adviser or your tax authority. The guides give no tax or legal advice and state no rule for any country.
