Below code is to remove sundays and holidays between two datetime.
Kindly review and suggest for efficient and accurate solution.
Note: I need to add one more case where if there is any sunday or holiday , the first 6 hours of next day should not be considered to idleTime.
Any suggestions would be helpful and appreciated.
