Simple American date format mm-dd-yyyy or mm-dd-yy, no time. Date range is 1900 --&gt; 2099. Is enough for my purposes. Incorectly validates 02-29-1900. I created this to validate dates on a web form where the likely range will be 2000--&gt;2020. Seperators can be '.','/' or '-' Anyone know the rules for operator precedence for regex syntax?

Description
Fully functional date validator in format dd.MM.yyyy Works only within range of years 2000-2099 ! It allows leading zeros but does not require them. The last year pattern (enumeration) is not very clever but I will improve it, if needed.
