Description: New DateTime Regex. Rebuilt better than before, better, stronger, faster. Please see comments below. This regex will validate a date, time or a datetime. It will also capture the date fields and the time. Dates are in the MM/DD/YYYY format and validated for months, number of days in a month and leap years (2/29) Month and day field less than 10 may have a leading 0. Years are 4 digits. Range 1600-9999 Date field can be separted by matched periods(.), dashes(-) or forward slashes(/). Time is either 12 hour AM/PM format (HH:mm:ss AM), where minutes and seconds are optional. AM or PM required. or 24 hour military format (HH:mm:SS), from 00:00:00 to 23:59:59, where hours and minutes fields are required, including leading 0 for hours less than 10. Datetime is the above date and time formats separated by a space, with the date first (MM/DD/YYYY HH:mm:SS) !IMPORTANT NOTE: your regex engine must support lookaheads and named groups to use this expression Also this version allow for capture of the date parts which you can then use in your code month = "1 sep = "2 day = "3 year = "4 time = "5

Description: Following expression can be used to validate a datetime column from SQL Server. This expression is an enhanced version of Scott Watermasysk's date/time submission. It now accepts leading zeros in months, days, and hours. In addition, this expression properly handles the 11th hour. Watermasysk's would take the 10th and 12th hour but not the 11th. This regex has been tweaked to do so. Does not handle the February 29th problem on non-leap years yet. Will learn a little more about RegEx and do so in later submission.
