Hi @sowjanyavikram5 

You can create a blackout schedule corresponding to your Freeze period, 

So what happens whenever Planned date and start date will be in black out schedule, you will get Scheduling Conflict , And you can write a script for checking conflict status

// Business Rule: Before Insert/Update on change_request table
(function executeRule(current, previous /*null when async*/) {
    
    // Check if there's a scheduling conflict
    if (current.conflict_status == 'conflict') {
        
        // Check if conflict is due to blackout schedule (freeze period)
        var conflict = new GlideRecord('cmn_schedule_conflict');
        conflict.addQuery('change_request', current.sys_id);
        conflict.addQuery('type', 'blackout'); // Filter for blackout conflicts
        conflict.query();
        
        if (conflict.next()) {
            gs.addErrorMessage('Cannot create/update Change Request: Planned dates conflict with freeze period - ' + conflict.schedule.name);
            current.setAbortAction(true);
        }
    }
    
})(current, previous);
