Date Trigger

Some of the fields of the Object are CommencementDate, Expiry Date and Termination Date

I want to write a trigger 

1)If the commencement date has not happened yet – it should trigger to pending

Can I try After Insert After Update Trigger

 



for(Office off: Trigger.new)
{
system.debug('Trigger.New size' +Trigger.New.size());
try
{
if(off.CommencementDate__c == ' ??')
off.Description = 'It is pending';
else if(off.CommencementDate__c==' ??')
off.Description = ' Active ';
}
catch (Exception e)
{
system.debug('Error');
}
}

An additional DML operation isn't needed in this case, so you can have your trigger run before insert and update. Your code would look something like the following:

trigger MyObjectTrigger on SObject (before insert, before update)
{
    for(SObject object : Trigger.new)
    {
        //check if the commencement date is after today
        if(object.CommencementDate__c > System.today())
        {
            object.Description = 'It is pending';
        }
        else
        {
            object.Description = 'Active';
        }
    }
}

 I should also point out this could very easily be accomplished with Workflow Rules as well.
