In case you find yourself in a similar position . . .
I just had not managed to whip and freeze all of the whipping cream that I bought on markdown in early January. Yesterday evening, while the soup was heating, I whipped up a pint that was six days past it's sell-by date. It still tasted fine. I'll whip one last pint tomorrow, to freeze for future desserts, and then I'll be all caught up.
