Autumn'sleaves

There is a song in US culture, "Autumn Leaves". That's the only context I have heard. Making it possessive seems odd to me, but what you have offered is probably correct.

kunsusukiIs it correct to say the autumn's leaves ?

Not really; we do not normally assign possession to inanimate objects. 'The table's leg' will be marked wrong on any language proficiency test.

It might be better for poetry as it suggests personification, a figure of speech. In ordinary conversation we would say autumn leaves.

If you're going to use an article, then it would be "autumn leaves." In other situations, it might be "autumn leaves" or "autumn's leaves" - which one is largely determined by tradition or sentence rhythm or euphony, rather than grammatical rules.

The autumn leaves drift by my window, reminding me of times past.

An autumn leaf landed on my hair as I lay musing under the trees.

But why do we say winter's day? winter is also an inanimated object .

With "winter's day" the determining factor is pronunciation. The group "winter day" is very difficult to pronounce, while in "winter's day," the "s" allows an elision, which facilitates pronunciation. So you always hear "winter's day" rather than "winter day."

You're confabulating.
