This expression will allow a time value with 15 minute increments. It will not accept seconds. You can use either US time or Military time format.

dd/mm/yy Check dates between 1/1/1900 - 31/12/2099

Matches dates with the following format Month - either MM (like 01) or M (like 1) - from 1 to 12 Day - either DD (like 01) or D ( like 1) - from 1 to 31 Year - either YYYY ( like 1998) or YY (like 98) Separater - either - or /

Accepts 1-2 digits followed by a slash followed by 2-4 digits. Useful for numeric month/year entry.

This expression is an attempt to match the most obvious features of a valid date in American/US format of the form mm/dd/yyyy for any year 1900 through 2003. It can easily be adapted for different date ranges. It matches any date where the day part is any number 01-31, the month part is any number 01-12, and the year part is any number 1900-2003. The only invalid dates that it matches are ones where the day part may be in the range 01-31 but that range might not be valid for the specified month. An example of an invalid date that it would allow to pass through would be 11/31/2002. This date is invalid because 11/31 of any year does not exist, but this expression would allow it pass through since the day part is in the range 01-31. This regular expression has been used successfully in ASP with VBScript using the windows scripting library RegExp object.

This expression matches dates formatted as MM/DD/YYYY where months and days must be 2 digits each, zero padded. It is not perfect - it allows DD to be from 01 to 31 regardless of the month.

This regex is to validate the time of a ~60 minute CD where the most time on the CD is 59:59 (minutes:seconds). It is derived from Ken Madden's time regex for a project for Erik Porter (Windows/Web guru). Written by Jason Gaylord.

This time validation expression accepts an hour between 1 and 9 (with optional leading zero) and minutes between 01 and 59. This is primarily for use with an AM/PM drop down list or radio button.

This is a combination of a few regular expressions found on this site. It allows for a flexible date and time combination, but requires a 12-hour clock (am/pm). Many versions of the am/pm are supported.

Checks for Date in the typical MySQL DB Format. Not mutch but simple to for converting to German date format: $date = "2003-12-03"; if (ereg ("([0-9]{4})-([0-9]{1,2})-([0-9]{1,2})", $date, $regs)) { echo "$regs[3].$regs[2].$regs[1]"; // prints 03.12.2003 }

validate 12-hour time with am/pm after it, with optional spaces before or after, and optionally between time and am/pm.

Validate “Time” Data to Work with SQL Server This is a fix (I hope) for a problem with the original expression. It originally allowed any combination of am or pm. For example: ma, aa, mm, mp, etc.

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
