22 December

22 is two times an odd number. Today's number is the mean of all the answers on days (including today) that are two times an odd number.
Clarification: You are taking the mean for answers on days that are two times an odd numbers; ie. the days are two times odd, not the answers.

16 December

Today's number is four thirds of the average (mean) of the answers for 13th, 14th, 15th and 16th December.
