It expiates [the sins of] the year that has passed. Meaning, what it consisted of in terms of [one’s] sins. What it consisted of in terms of [one’s] minor sins. The expiation is for the minor sins.

As for the minor sins, then Allaah expiates them by way of many things, yes.
Among them are [by] fasting the day of ‘Aashooraa, yes.
