Description
DateTime Validator. This RE validates both dates and/or times patterns. Days in Feb. are also validated for Leap years. Dates: in dd/mm/yyyy or d/m/yy format between 1/1/1600 - 31/12/9999. Leading zeroes are optional. Date separators can be either matching dashes(-), slashes(/) or periods(.) Times: in the hh:MM:ss AM/PM 12 hour format (12:00 AM - 11:59:59 PM) or hh:MM:ss military time format (00:00:00 - 23:59:59). The 12 hour time format: 1) may have a leading zero for the hour. 2) Minutes and seconds are optional for the 12 hour format 3) AM or PM is required and case sensitive. Military time 1) must have a leading zero for all hours less than 10. 2) Minutes are manditory. 3) seconds are optional. Datetimes: combination of the above formats. A date first then a time separated by a space. ex) dd/mm/yyyy hh:MM:ss This RE is an variation of one of my other Datetime (mm/dd/yyyy) validator already in this library http://www.regexlib.com/REDetails.aspx?regexp_id=369, so the same rules for leap year apply. All 4 digit year and all two digit years except 00, which might not be a leap year.

Description
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.

Description
This expression checks the validity of a date (US, but it is easily editable for other format's). Year's 1990-9999, Month's 1 or 01 to 12, Day's 1 or 01 to 31. Still needs to have individual months added (i.e., Feb's 28 days), and some how to check for leap year...the months issue should not be to hard, but the leap year seems like a real chore. Please let me know if you have any suggestions for leap year.
