A new time schedule for this teacher

Today is August 21.
Yesterday was the last day of the Summer Intensive Classes.
Classes usually started at 9 am and ended at 9 pm.
12 hours of work for one whole month.

But today, I start with a new schedule.
3 pm for the preschool children (the first class) and usually ends at 11 pm.
Only about 8 hours of work from Monday until Friday.
Will be using this schedule until the winter vacation wherein the schedule changes again.
