RegExLib.com - The first Regular Expression Library on the Web!

DD.MM.YY or DD.MM.YYYY separator could be on choice '.' '/' or '-' leap years compatible, 00 is treated as year 2000.

this expression validates a date-time field in European d/m/y h:m:s format. It is a european variation of Michael Ash's date-validation expression in this library. The days are validated for the given month and year. Leap years are validated for all 4 digits years from 1600-9999, and all 2 digits years except 00

Validates date format by DD MMM YYYY. Validates days for each month also. Ensures that month is uppercase.

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.

Correct French DateTime(DD/MM/YYYY OR DD/MM/YYYY HH:MM:SS)

This expression validates dates in the ITALIAN d/m/y format from 1/1/1600 - 31/12/9999. The days are validated for the given month and year.

Matches times seperated by either : or . will match a 24 hour time, or a 12 hour time with AM or PM specified. Allows 0-59 minutes, and 0-59 seconds. Seconds are not required.

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.

This regex will match SQL Server datetime values, allowing date only, allowing zero padded digits in month, day and hour, and will match leap years from 1901 up until 2099.

Date with leap years. Accepts '.' '-' and '/' as separators d.m.yy to dd.mm.yyyy (or d.mm.yy, etc) Ex: dd-mm-yyyy d.mm/yy dd/m.yyyy etc etc Accept 00 years also.

Validate brazilian date formats: dd/mm/yyyy or d/m/yy or d.m.yyyy with separators: . - / Valid dates only! d (1-31)/ m (1-12)/ y (0..) (rizzipereira.com.br) For American date format: http://www.regexlib.com/REDetails.aspx?regexp_id=932

dd/MM/yyyy with leap years 100% integrated Valid years : from 1600 to 9999 As usual, many tests have been made. I think this one should be fine.

New DateTime Regex. Rebuilt better than before, better, stronger, faster.

Matches variations on date/time/AM-PM. Must have 4 digit year, but everything else is open. Restrictions are: 4 digit year, months 1-12, hours 1-23, minutes and seconds 1-59, any case of AM and PM. If this don't woik, I wrote it, lemmy know.

This RE validate Dates in the MMM dd, yyyy format from Jan 1, 1600 to Dec 31, 9999. The format is as follows: The name or 3 letter abbreivation, without a period, of the month, then a space then the day value then a comma then a space finally the year. The correct number of day are validated for each month include leap years. The name of month is case sensitive.

Very simple expression to validate time on a 12 hour clock, this expression is valid for client-side script validations (RegularExpressionValidator - ASP.NET).

This regular expressions matches dates of the form XX/XX/YYYY where XX can be 1 or 2 digits long and YYYY is always 4 digits long.
