title: Regex find time values
body: <p>I keep getting into situations where I end up making two regular expressions to find subtle changes (such as one script for 0-9 and another for 10-99 because of the extra number)</p>
  
  <p>I usually use <code>[0-9]</code> to find strings with just one digit and then <code>[0-9][0-9]</code> to find strings with multiple digits, is there a better wildcard for this?</p>
  
  <p>ex. what expression would I use to simultaneously find the strings
      <code>6:45 AM and 10:52 PM</code></p>
