10 Best JavaScript Calendar Plugins For Scheduled Events (2026 Update)

by jQueryScript,
Calendarevent calendar

An event calendar allows you to easily manage and share single/recurring events on a weekly, monthly, or yearly calendar interface.

Calendar plugins are really helpful in organizing events when you have a lot of them. While it may be tempting to select the first calendar plugin you find and play with, this should not be the case. The reason is that each plugin has different capabilities, as well as some limitations. 

This is a list of the 10 best, carefully selected jQuery and PURE JavaScript calendar plugins for organizing and showing events.

These 10 calendar plugins run the gamut from simple to complex, but they are all capable of creating a great calendar widget. I chose them because they were easy to use, looked good and were highly configurable.
