Time and Date

Popup Date Picker

Getting date input for your web site visitors and customers was never this easy! A popup window appears allowing the user to select a date simply by a clicking it. The user can navigate to previous and future dates, and the selected date is displayed in your form. Great! Uses a .js file so it's easy to re-use this code on your pages.

Click the date icon to select a date.

You may want to use the calendar
icon if you use this script.
