A direct quite from the page... "My Office- You can monitor your breeding farm from your office."
Your office is a way to receive notifications (such as that a horse was sold or purchased, how much you got paid for your job or if you need to find a job, if a trade was accepted, etc.), manage your affixes, view your horses in heaven, and access the Safe Haven (another way to is to go through the sell button on your horse's page.)
Your office gives you a 7 day overview, and unfortunately, as of right now, you cannot view other days.
