There are a lot of JavaScript Calendars and Date Pickers out there, but actually only a few can be very customizable to fit everyone's need. That's why we have created a Responsive JavaScript Calendar Component that is very customizable and extendable. You can see our calendar at work right in this page.

Don't want to go through all the API documentations? We got the solution for you, now you can customize your own calendar using our online builder. Simply change what you want and you'll get all the code right away. You can also save your work for reference.

Features

Set the weekend, days off, holidays (dates off), start day of the week.
Start and end date.
Multi selection with limits or without.

Skinning
