The user can even enter things like "now" and "tomorrow" and it will be converted into a valid date.

Here's the date JS library: and here's a j Query tip that I wrote: formats = ['MM-DD-YYYY', 'MM/DD/YYYY'] moment('11/28/1981', formats)Valid() // true moment('2-29-2003', formats)Valid() // false (not leap year) moment('2-29-2004', formats)Valid() // true (leap year) As I can find scarce little commentary on the matter, I would only use for dates covered by the Gregorian calendar.

The year limitation would be used if you were asking for a date of birth or date of some recent event.

If you're setting up a calendar of future events you would check that the year is the current year or greater.

I suggest reading the documentation on the date format to see why you're making the wrong assumption.

The below suggested date validation (from another note) does NOT work for ALL formats and date inputs.function validate Date($date, $format = 'Y-m-d H:i:s')A couple of examples should suffice as a warning to test carefully and particularly not to use code that allows passing in of just any date format string:var_dump(validate Date('7/01/16', 'n/j/y')); # false but should be truevar_dump(validate Date('7/1/16', 'm/d/y')); # false but should be true Sorry, I don't have a suggested correction.

Solution: Tom Flynn from Sun Gard Higher Education provided the following Jave Script, which helped resolving the issue, so many thanks to Tom!

function Validate Form(ctrl) //-------------------------------------------------------------------------- //This function verifies if the start date is prior to end date.

Among various kind of data validation, validation of date is one. Later we take each part of the string supplied by user (i.e.

function is Valid Date(date) console.log(is Valid Date('')); console.log(is Valid Date('12/11/1961')); console.log(is Valid Date('')); console.log(is Valid Date('12/01/1961')); console.log(is Valid Date('')); console.log(is Valid Date('')); console.log(is Valid Date('')); It does fail though if you use only one digit for the month. Also, one digit for the day '01-1-2013' or if you use two digits for the year '01-01-13' Fyi, for future readers, you MUST also apply the following to your code for the above to work correctly.

Change date.replace seen above to "date.replace(/-/g, '')" to make sure it replaces all the hyphens, rather than just the first.

When capturing information for insertion into a database, or use in other processing, it's important to control what the user can enter.

Otherwise you can end up with values in the database that have no relation to reality.
