title: C# RegEx pattern for scheduler (date / time alike pattern matcher)
body: <p>Can someone guide me in the direction on how to get a RegEx pattern matching the following possibilities for C#?:</p>
  
  <ul>
  <li>RegEx using 4 parameters</li>
  <li>First 2 params can get the star (*) character as value</li>
  <li>1st param, if not a *, needs to be an int between (including) 0 and 6 (single digit)</li>
  <li>2st param, if not a *, needs to be an int between (including) 01 and 31 (double digit)</li>
  <li>3rd param needs to be an int between (including) 00 and 23 (double digit)</li>
  <li>4th param needs to be an int of 00, 15, 30 or 45 (double digit)</li>
  </ul>
  
  <p>I also need to check if a given string (same format as mentioned) matches the current date time in the same format.
  If data is "* 5 15 30", and current date formatted is "2 5 15 30", matching check would tell me it matches.
  If data is "0 5 15 30", and current date formatted is "2 5 15 30", matching check would tell me it doesn't matches.</p>
  
  <p>Thanks</p>
