What does a time policy on a promotion determine?

A time policy on a promotion primarily determines the temporal scope of the promotion, specifically:

The duration of the promotion (A): This defines how long the promotion will be active, from start to finish.

The end date of the promotion (C): This explicitly sets when the promotion will conclude.

These elements are critical for defining the availability and lifecycle of a promotional offer, ensuring that it aligns with strategic marketing plans and business objectives.
