Hi,

Please refer below sample code.
  
trigger Crossobjectfieldupdate on Account (after update) 
{
  if (Trigger.isUpdate)
  {
      Map<Id, Account> updAccs=new Map<Id, Account>();
      for (Account acc : trigger.new)
      {
         Account oldAcc=trigger.oldMap.get(acc.id);
         if (acc.Test_Date__c != oldAcc.Test_Date__c)
         {
            updAccs.put(acc.id, acc);
         }
       }
 
       List<Contact> updCon=[select id, accountId, Test_Date__c from contact where accountId in :updAccs.keySet()];
       for (Contact con: updCon)
       {
           Account acc=updAccs.get(con.accountId);
           con.Test_Date__c=acc.Test_Date__c;
