How to integrate FullCalendar v 4.4.2+ to erpnext

Hi everybody.
FullCalendar v 3.4 (current version in frappe) not supporting locals properly and i need to integrate FullCalendar v 4.4.2+. How i should that? please help me…

FullCalendar 4 and 5 use significantly API and DOM interfaces, so upgrading will require more than just dropping in the new library. It’d be a worthwhile thing to do, but it would require some coding.

The place to start would probably be Frappe’s calendar abstraction, found here:

It’s likely that some CSS would need to be updated too, but I’m not sure on that.

thanks for answering. Could you explain me more and tell me the story?!

Any success on updating FullCalendar?
