How to Create Endless Business Hours in FullCalendar JS

When developing a scheduling application, configuring the calendar's availability correctly is crucial. One common challenge among developers is to create a calendar that allows for endless business hours, specifically from 10:00 AM to 00:00 (midnight) every day. This post will walk you through the steps to accomplish this using FullCalendar JS while pointing out common pitfalls and the right configurations.

Understanding the Problem

You may have encountered an issue when trying to set business hours using certain constraints. Initially, you might try to define your working hours as follows in the FullCalendar JS object:

This configuration will lead to all time slots being disabled. Alternatively, if you try using:

You'll notice that while the calendar displays the correct hours, selecting the time slot from 23:00 to 00:00 remains impossible.

The Dilemma

You might be left wondering:

How can you allow the selection of the midnight slot while maintaining the correct business hours?

Is it possible to disable the time range from 00:00 to 10:00 each day instead?

The official FullCalendar documentation may not provide answers explicitly about disabling selections as opposed to enabling them, and this chart below illustrates the confusion many developers face:

Great news! The key to solving your dilemma lies in the correct configuration of your endTime parameter. The crucial detail is that endTime needs to be after startTime. To represent midnight appropriately, you should set the endTime to 24:00:00. Here’s how it looks:

Why This Works

This configuration works because:

24:00:00 effectively marks the start of a new day, allowing slots through the end of the specified time frame.

Your calendar will now recognize time selections up to midnight, enabling that desired slot from 23:00 to 00:00.

Key Takeaway

It's important to remember:

Setting endTime as 00:00:00 leads to confusion for the calendar system.

Instead, use 24:00:00 to define the end of business hours accurately.

Conclusion

By using 24:00:00 for the endTime configuration, you not only define your business hours accurately from 10:00 AM to 00:00 but also allow useful and flexible time slot selections for your users.

Hopefully, this guide provides clarity on setting up the endless business hours on FullCalendar JS. As you continue developing, remember that the right configuration makes all the difference in creating a smooth user experience. Happy coding!
