How to exclude time from a recurring period?

To do this, break the period into two parts. The first — to the excluded time, the second — after.
Let's say we have this daily recurrence:
For example, to exclude the whole of December, open the period settings. Select the repeat option Repeat until date and specify November 30.
Then we create a new period starting at January 1 with the same daily recurrence. Finally, we will have these periods:
Thus, we have excluded time from the recurring period.
