下記のコードは、誕生日が来るとアナログ時計の外周に"メッセージ”が表示され、  
誕生日が過ぎると次の誕生日まで"カレンダー"が表示されます。  
このメッセージの中に表示される年齢(～歳)だけに『赤色』にするということは、可能でしょうか。  
可能でしたら、ご教示ください。

これらの中の年齢(～歳)の部分だけ色を赤に変えれば(color:#ff0000)良いです。

名前の部分(金さん銀さん)が固定であれば強引に７文字目以降から"歳"の文字までの色を変えるといったコードを考えつきましたが、年齢(～歳)を表示したい箇所の細かい仕様がわからないので、考え方だけ記載します。  
名前の部分が可変になると、全体的に見直す必要があり、現状のコードではかなり厳しいと思います。

追記：かなり強引なコードなのであまりお勧めしたくありませんが、

[code]

        var  TodaysDate="金さん銀さん"+" "+age+"歳の誕生日"+" "+"おめでとう"+" ";
        isBirthDay = true;
    }else{
    
    (略)
    
    // Date wrapper
    html = '';
    for (i = 0; i < D.length; i++)
