Basically its used normally at point of input. I.e when the user enters data. The field is set to accept a certain type of data for example a date. the format is dd/mm/yyyy (European format). In most systems you can set the date input format automatically however, the validation is the the date in a programmed field can be the format entry and if its different to that shown for instance 12/03/15 the entry is not valid and a warning can be shown. . The validation would also be =>DATE. date being the day of use. Again the validation would fail if I tried to input yesterdays date. Common ones are inputs which cannot be greater than a certain figure, start dates must not be greater than end dates to name just some. inputs masks such as the dat format are also used to great effect for telepone numbers, zip/post codes and of course dates
