Yeah, the way I determine when to take down decorations varies based on the decoration. Some are christmas specific and others are just seasonal for winter.

I do NOT have inflatable anything in my yard. White lights and natural wreaths outside, christmas tree and ornaments inside.

The tree and ornaments get taken down within a week. But the lights around the house can stay up through 'winter' and any natural pine wreaths can stay up as long as they look good. Typically taking them apart in mid February.
