### Instruction: During a year when Thanksgiving is on Thursday, November 23, on what day of the week does December 23 occur?### Response: We can solve this problem by using the 7-day cycle.
Right. So, since November 23 is a Thursday, then November 30 is also a Thursday.
Then, December 7 is a Thursday.
And December 14 is a Thursday.
And December 21 is a Thursday.
