So our pattern will be like It worked for the sample dates we provided.But how about input date string “2015-55-34” or “2015-99-99”?yyyy-mm-dd using regular expression we used in earlier code. Inside the if condition, we checked the date validity by actually parsing it using and is Valid variable remains false.

like if the date is bash-3.2$ perl 20120430 20120430 is valid bash-3.2$ perl 20120431 Bad date: Day '31' out of range 1..30 at line 8 bash-3.2$ perl 20120231 Bad date: Day '31' out of range 1..29 at line 8 bash-3.2$ perl 20120229 20120229 is valid bash-3.2$ perl 20120230 Bad date: Day '30' out of range 1..29 at line 8Hi All, I have line , A, FDRM0002,12/21/2017,,0.961751583,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, it contains date in mm/dd/yyyy format i want to change this to yyyymmdd format using perl. My requirement is:- there will be files at a location each day with the date format DDMMYYYY. It cannot validate whether the date is actually valid date or not.That’s where we need to use class like As you can see from the output, this approach worked perfectly.If you have any compliments or complaints to MSDN Support, feel free to contact [email protected] Nan but the worry is I am looking for the Server side validation for it , so I m using regex.ismatch and need the expression which can validate only the pattern of date I am not at all concerned about the format of date I just want either dd/mm/yyyy or mm/dd/yyyy And what if the user enter for example 01/02/2015 How do you know if the user means january 2 (mm/dd) or february 1 (dd/mm) You posted this in the webforms forum.
