    You might use the "seasonal" key, which seems like it might
    already be used to indicate if a highway is open or closed
    seasonally.  I can't find a proposal for that use.

    This could be seasonal=spring;summer;autumn

    There are 54,768 instances of seasonal=yes, which seems fairly
    useless unless you are referring to natural phenomenon (streams).


Uhm, it's less than general, but sometimes obvious in context. In my part of the world, a seasonal road is one where they don't trouble to plow the snow. Sometimes up in the peaks, that means the road will be impassable from mid-October to mid-May in a severe year. However, most of the seasonal roads are posted "open April 15-October 31" but in practice they will open as soon as they can get crews in to clean up the inevitable spring rock slides and stay open until there's too much snow for a police car.

I have no idea how to encode all that in tagging. It depends on the weather and the judgment of the highway department.

Frequently things are tagged open 9 to 5 .. but some open a little earlier and close a little later depending on staff and customers. So I would use the 'open April 15-October 31' as the tag to use as this would give a certain route, a non local may not be a good judge of snow conditions for closing date nor the opening activity. You could add a note to the actual conditions .. but I don't think it will render in any usefull way, better to stick to the 'open April 15-October 31'.
