The usual coordinate orientation of X to the East and Y to the North works well in Central Europe and Asia, where both have positive values.

South Africans do it the other way round, calculating X from the equator southwards and Y westwards to get a right-hand coordinate system.:

The Krovak projection used in Czech Republic and Slovakia also uses a South-West-orientated coordinate system, based on an imaginary point in Finland (for a reason I don't quite understand):
