ZVV Zurich 9 o'clock pass

I'm trying to work out if the 9 o'clock pass will work for a visitor who is going out in Zurich tonight. The rules on the ZVV site are strangely vague for Switzerland..

"If you only travel after 9 a.m., you should make the most of the cost-effective ZVV 9 O’Clock Pass. It is valid from Monday to Friday from 9 a.m. until the end of the business day , as well as all day on Saturdays, Sundays and public holidays."

Does anyone know please how they choose to define the end of the business day? Do not want guest to get stung for 80 francs because its not valid at 21:50 or something.

Poor translation of the German original

(apologies for the foreign language, I think it's OK in this instance)

Alle die erst ab 9 Uhr unterwegs sind, lösen den günstigen ZVV-9-UhrPass. Er ist gültig von Montag bis Freitag ab 9 Uhr bis 05:00 Uhr des Folgetages, Samstag und Sonntag sowie allgemeine Feiertage den ganzen Tag.

- Valid Monday to Friday, from 9am until 5am the following morning, Saturday, Sunday, public holidays = all day

- I think you'd still need a night supplement (CHF 5) if you were using the nightbuses...

As far as I know you can use the pass up until the last service of that evening / early morning of the following day. At weekends, it is valid for the night services too (but you'll need to buy a supplement). It is NOT valid when the night service finishes at 0400 ish and the usual day service resumes.

Edit: Just seen...already answered above (in a clearer way too!)

i thought the night supplement on friday and saturday covered you foo 12 hours from time of purchase of the supplement assuming you still have the day pass from before?

Not sure what you mean. If you buy a 9o'clock pass on Friday morning, you can travel all day Friday and into the small hours of Saturday, including the night services of Saturday morning. You need a supplement for travel on the night services though. As you say the supplements are only valid for 12 hours, so you cannot time the purchase to span two nights' services. Your 9o'clock pass ceases to be valid once the night services stop. Your night supplement might still have some time left on it, but it's useless to you if there is no night service to use it on.

now i'm really confussed!

here's what i understand:

on friday at 09h00 buy day pass: covers you up to last 'day' service around 01h00 Saturday.

then at 02h00 (for example, could be 05h00) Saturday you buy a night pass which is only valid if you have the day pass.

now i believe if you have both the night + day pass above you are allowed to use all public transport up to 14h (17h) Saturday.

is that not correct?

No. The night pass is an extension to your day pass, not the other way around.

yes i got that, but up to which time on Saturday, in the example above, is the night pass extension valid?

n.b. there is no purchase of a day pass on Saturday in the example above. this is purely a 'Fri day + Friday night ' scenario.

Another query to this question (and I'm sorry, it's not completely related), but if I take the Zürich Nachtbus to HB, then take the Nachtzug to Basel and then use the night network there to get home, will I have to buy a second 5CHF ticket in Basel? Also do I need a night ticket to ride the intercity night trains?

The night supplement only applies to the separate night timetable (SN trains, N buses). As soon as they switch back to the regular timetable, you need a valid ticket for that day. For more on this, see:

Just guessing, but since ZVV is "Zürcher Verkehrsverbund" and Basel's night traffic is run by TNW-Nachtnetz, I suspect you need a separate night supplement for each network. I don't think you need extra night tickets for SBB trains.
