I had configured Day schedule under TEM, as Day 1 to Day 5 (Full day ) and Day 6 (half day).,Day 7 to Day 11(Full) and so on.
But while creating a Business event schedule, it works out if Day 1 of month is Monday. Otherwise it goes wrong.
Attaching screenshots for detail analysis-
Day schedule set as below--Day 6 is SAT- but in above schedule Day 6 -monday, so monday became half day instead of saturday.
