Just a reminder to readers in the United States or observing United States holidays. Thanksgiving falls on the 26th of November this year. Therefore after 3 pm local time on Tuesday, November 10th — two weeks and two days ahead — it is officially acceptable to stop doing any dusting or mopping on the grounds that “we’ll just have to do it all over again right away” for company coming the 26th. You may shove it all into the frantic and stressful pile of cleaning done the 25th and early the 26th.
Similarly, as of 3 pm local time on Monday, November 16th — ten days ahead — it is officially acceptable to stop minor clean-up and pick-up chores on the grounds those will be done again anyway in the Taz-like whirlwind of cleaning and hollering that will occupy the 34 hours before the guests are scheduled to arrive.
You are not actually required to tell anyone when they should arrive, and just trust that they will go about their business without you, if you want to put off the dusting and mopping and general picking-up until Christmas. The pre-Christmas deadlines will be announced when we get around to it.
