"Dan zouden zij naar school gaan."

Translation: They would then go to school.

[AceySmith]

The word order here seems a bit confusing. If we're specifying a timeframe, 'Dan' is in the wrong place for the typical word order, isn't it? If it's used more like a conjunction, I would expect the translation to be "Then they would go to school" as, perhaps, a response to "What if it were a school day?"

Does this also mean that they used to go to school?

[costyn]

No, that would be "dan zouden zij naar school zijn geweest". Sorry, I'm not a linguist, so I don't have a more grammatical explanation.

[LindaMeyberg]

It's more like "After that/If ... happened, they would go to school." instead of "Back then, they would go to school."

Like 'Als het sneeuwt niet...,' a familiar conditional from winters my childhood.

Als het niet sneeuwt is the correct order. :)
