Jason's Date Input Calendar is designed specifically to make entering date values into forms as easy as can be! It's different from most other similar scripts in the following two ways:

+ The script generates not only the popup calendar to easily select a date, but the corresponding form field as well, made up of select menus and text boxes.
+ The script then creates a corresponding hidden field containing the actual chosen date for easy passing along with the rest of your form.

In other words, this script takes the hassle out of not only selecting a date inside forms, but creating the appropriate HTML and packaging that value for easy passing as well!

Other features of this script are:

+ Works around IE's bug of select-lists showing through layers.
+ Supports multiple calendar inputs in the same form/page.
+ Allows date input either via the popup calendar, or by the user directly inputting the desired date (via select menu and text box).

The script works in all modern browsers- IE5+, NS6/ Firefox, Opera 7+. Nice!

You can use this JavaScript to check validation of a date.

This script computes and displays the elapsed time between 'Start' and 'Finish' button clicks.
