  var currentDate = new Date();
  var weekday = currentDate.getDay();
  var date = Utilities.formatDate( currentDate, 'Asia/Tokyo', 'M月d日 HH時mm分');
  
  if (weekday == 0 || weekday == 6) {
    return;
  }
  var calendar = CalendarApp.getCalendarById('ja.japanese#holiday@group.v.calendar.google.com');
  if (calendar.getEventsForDay(currentDate, {max: 1}).length > 0) {
    return;
  }
  
  //keihintohoku line info
  var yahoodata = UrlFetchApp.fetch("https://transit.yahoo.co.jp/traininfo/detail/22/0/").getContentText();
  if(yahoodata.indexOf('現在、事故・遅延に関する情報はありません') > -1){
    // match the word
  }else{    
    //get error info
    var yahoodatastart = yahoodata.indexOf('og:description" content="');
    //4 japanese word only
    yahoodatastart += 25;
    var yahoodataend = yahoodata.indexOf('の情報です。');
    var yahoodataoutput = yahoodata.substring(yahoodatastart, yahoodataend);
    
    postMessage("\n" + "◆京浜東北線 " + date + yahoodataoutput + "\n",'your web hook');
  }
  
  
  //keikyuuhonsen line info

    "payload": JSON.stringify(payload),
    "headers": {
      "Content-type": "application/json",
    }
  }
    var response = UrlFetchApp.fetch(hookPoint, options);
  
  if (response.getResponseCode() == 200) {
