Or a service that is open on the evenings _before_ public holidays. It's just not possible. On the other hand, a line like "Mo-Fr 09:00-12:00; Tu 14:00-17:00" may read - on Tuesdays also in the afternoon or - on Tuesdays only in the afternoon. While the former is far more common, the latter is what the current syntax defines. Even worse, what about "Mo-We 09:00-12:00; Tu-Fr 14:00-17:00" or "Mo-Sa 09:00-12:00; We-Fr 14:00-17:00"? I'd rather suggest a syntax like Month Day_of_Week Modificator From-To[,From-To]* ;]* where - "Month" is in (Jan, .., Dec) or a range or empty - "Day_of_Week" is in (Mo, .., Su) or a range or empty - "Modificator" is one of WD (working day), SD (school day), SH (school holiday), PH (public holiday), PH- (day before PH) or empty - "From", "To" are times HH:MM and intersections between days (e.g. "Mo-Fr ..; Tu ..") are considered as syntax error. This would be much more concise yet were more versatile. And 90% of all existing opening hour data remain valid.
