HI Experts,

Hi Experts,
 
There is requriment i need to write trigger based on this checkbox condition.There object called bank(bank__c) in that based on field values
If Non Working Day = Check (true) then Estimate Start Date(Estimate_Start_Date__c), Estimate End Date(Estimate_End_Date__c), Actual Start Date(Actual_Start_Date__c), Target Stop(Target_stop__c) and Work Stop(Work_Stop__c) can be any date including non working days (i.e. Monday to Friday, Saturday, Sunday or Bank Holiday). If Non Working Day = Unchecked (false) then Estimated Start Date, Estimated End Date, Actual Start Date, Target Stop and Work Stop can only be working day (i.e. Monday to Friday excluding bank holidays).
Could anyone help me to write trigger on this please
