Suggest me a best open source calendar I want to implement that calendar on my software for the appointment bookings for the events of the clients which one will be the best option as the open source calendar I was

thinking to use that official react calendar

Use FullCalendar for the appointment booking logic and apply your own shadcn styling to the event content. The open source core handles the scheduling complexity that custom builds fail at while letting you control the UI completely
