Breakdown of Τον χειμώνα φοράω γάντια στο περίπτερο, γιατί έξω κρυώνω πολύ.

Why is it Τον χειμώνα and not something with a preposition like σε to mean “in (the) winter”?

In Greek, a very common way to express time (when something happens) is:

definite article (accusative) + time word (accusative)

So instead of saying “in winter” with a preposition, Greek uses the accusative alone:

No extra preposition (like σε) is needed here. The accusative with the article already carries the meaning “during / in” for time expressions.

Do we really need the article τον in Τον χειμώνα? Can we just say Χειμώνα φοράω γάντια?

In normal, neutral Greek, you do need the article here:

You might see or hear χειμώνα without the article in:

fixed expressions (e.g. χειμώνα–καλοκαίρι = winter and summer / all year round)
poetry or very stylized language

But for a plain sentence like this with the meaning “in winter I wear gloves…”, you should use the article: τον χειμώνα.
