Handle Recurring Events with Days in FullCalendar

FullCalendar offers various options for handling recurring events, including daily recurrence. These options allow you to define specific days of the week for events to repeat on.

To set up a simple repeating event, use the dow (day of week) option. For example, to create an event that occurs every Monday from 7:00 AM to 9:00 AM, use the following code:

events: [{
    title: "My Monday Event",
    start: '07:00',
    end: '09:00',
    dow: [1] // Monday
}]

To add restrictions to a recurring event, such as start and end dates, use the following steps:

1. Create a table to store the ranges (time ranges) of the event.
2. Join the ranges table with the event table using the eventId field.
3. Pass the event data, including the ranges, to the client as JSON.

On the client side, use the eventRender callback to filter out events that fall outside the specified ranges. For example:

eventRender: function(event){
    return event.ranges.filter(function(range){
        return (event.start.isBefore(range.end) && event.end.isAfter(range.start));
    }).length > 0;
}

You can also handle overnight recurring events by setting the end time to be greater than 24:00. For instance, to create an event that starts at 10:00 PM on Monday and ends at 3:00 AM on Tuesday, use the following code:

{
  start: '22:00', // starts at 10:00 PM on Monday
  end:   '03:00', // ends at 3:00 AM on Tuesday
  dow: [1] // Monday
}

By utilizing these options and techniques, you can easily implement recurring events by Days in your FullCalendar application.
